A couple more things regarding Chrome hardware: I don't know that they make sense if you want to avoid running Chrome OS--buying Chrome hardware, practically speaking, means buying into Google's ecosystem on some level. But I do appreciate that a Linux container installation is one-click away, and it's well integrated enough that it might as well be native, albeit with providing good security/recoverability isolation. The idea that you can purchase a $200 Chromebook for an interested kid and they can go off and learn how to code Python or Ruby or whatever with little effort is a big benefit. Sure you can do that on a Mac, but those are expensive, and I guess you could do the same with Windows and WSL (or Cygwin) but I don't think you can do that on a comparably-priced "Windows S" machine. Or maybe you can--I don't follow that. I was also really attracted to Chrome hardware because I felt that they really thought about how to do secure/attested devices the right way. There's multiple layers of security in place to minimize unknowing compromise and ensure easy recovery should something happen. But at the same time they made openness a requirement, which is why they allow progressively-greater access to the raw hardware for someone with enough inclination, time, (and physical access) to open the machine up. It would've been easier for them to lock the machine down hard and say "forget it".

I bought a new chromebook and it errors out when enabling the linux vm/container without any useful message. Pretty drat annoying. Overall it is like using some gnome-like thing where there are even less configuration options. And I complain about that as someone who enjoys gnome3.

Does anyone know much about how abrt works? I'm on Centos 7 and I've been chasing the cause behind a couple machine check exceptions that keep popping up during every startup. I think what's happening is that abrt keeps showing me these old problems because the timestamps on the problem directories are always the same. I'm now pretty sure that the original exceptions were caused by me trying to undervolt too much, which I am not anymore. So I go to delete the problems with "abrt-cli rm <dir>" but then the exact same directories come back after a reboot and abrt continues to show them to me. Any idea what's going on? I guess it doesn't really matter because the computer works fine but it would be nice if I could satisfy my OCD by having it stop telling me it encountered a problem several months ago. Edit: Well I figured it out. The errors I got were dumped into /var/crash and abrt parses that directory so that's why they kept coming back. I just needed to delete those too and all is good.

Another BTRFS question. Is it possible to achieve the following configuration? - Two physical drives of different capacity, let's say the small one is 2TB and the big one is 3TB - Two data folders: /important and /unimportant (could also be /data and /data/important if it makes things easier) - The data under /important is replicated in RAID1 on both drives - The data under /unimportant is not replicated (single mode) - Both drives live in a single JBOD-esque filesystem, and I don't have to manually choose how to split the total (A+B) capacity - End goal: I'm free to write either Important or Unimportant data without periodically janitoring the partitions. The Important data will be duplicated, so I can potentially write up to 2TB of Important data, in which case I would have 1TB left for Unimportant data on the big drive. Realistically, the ratio between Important and Unimportant data is gonna be between 1:10 and 1:100, so I won't have a lot of balancing problems. I just want to avoid having to guess partition sizes if possible.

When I checked for a similar function it was planned and an experimental buggy mess. It might stop be in that state of even having been abandoned. Or maybe it works now, but certainly was less of a priority then raid5. It would work by setting a file or directory to single mode, similar to the function for compression.

NihilCredo posted:Another BTRFS question. Is it possible to achieve the following configuration? No: you within a single btrfs volume you can have subvolumes, but you can't have different mirror/stripe options per subvolume. (Yet, it's a wishlist feature, but who knows when it will happen.) A btrfs raid1 drive pool can use 3 or more unequal size drives to get the maximum capacity that is possible (ie 2TB+3TB=6TB = 10TB capacity), but that's still mirroring on everything. btrfs isn't a terrible choice for your setup because it's relatively fast to resize volumes, much more than ZFS. But you're still gonna be doing everything manually when you want to change the balance of Important and Unimportant.

Wait, btrfs doesn't have an equivalent of ditto blocks? On zfs, you set copies=2|3 which tells zfs to write the same block multiple times on the vdev that the dataset is on*. I believe this function is essentially reusing the exact same code for metadata, which also gets written multiple times to disks. *: It's not an even distribution, hence it's not a replacement for the actual mirroring or striped data with distributed parity - the primary use-case is if you've got a machine which can't fit multiple drives and you want some protection against UREs without having to resort to backups.

I would like to automate the downloading of Linux isos on my EndeavourOS install (Arch derivative), something that was trivially simple on Windows, using Sabnzbd and Radarr. I have done my best at googling, and it seems the simplest way for me to do this is to run the radarr.service as my own user, by editing it and adding changing the user and group in the override section. I have <indicated> where I figure I need to make changes. code:code:I'm hours away from going back to Windows to avoid all these permissions headaches. I just want to download Linuxeses.

Who's the owner of the download folder? Does it have permission for you to write? Does it work if you leave the group as radarr?

The folder is owned by my user. If I leave the group as radarr I cannot access the folder. I've read so much on folder permissions and users and groups, my brain has gone blurry.

yeah, we'll need to go up in the journalctl output, the "at NzbDrone.Common.EnvironmentInfo.AppFolderFactory.Register() in D:\a\1\s\src\NzbDrone.Common\EnvironmentInfo\AppFolderFactory.cs:line 55" line at the top is clearly cut-off output of the error.

The problem is it can't write to /var/lib/radarr. You either need to make that location and the existing files writable by jt4527 or change the "-data=/var/lib/radarr" part of the service file to write to a location owned by jt4527.

That should work. Put a recursive -R on there. That said; why does the default install run as root and why do you need to run it as not root?

I've no idea why it runs as root, but when I try and setup up my folders in radarr I only have access to the top level directories and when I click save, it says the directory is not writable by the user radarr. I just want to run the service as a user I know has access to the files and folders.

You should probably fix it so it doesn't run as root. On FreeBSD, daemon(8) can drop privileges for any arbitrary program or script - I'd be shocked if Linux can't do it somehow.

Sorry, I may have misread radarr as root, confusing the issue. A quick google shows install notes that say: User=radarr Group=media If you want access radarr content as jt4527, then you could also add that account to the media group code:Or you add the radarr user to a group that gives it permission to access a folder owned by jt4527. But not being familar with radarr, how you machine is exactly setup or exactly which directories you want radarr to write to, it's hard to provide exact solution. In theory you've lost a bit of security benefit of separation between radarr and your normal account (eg radarr has a flaw that allows an attacker a foothold and they can immediately pivot to stealing your browser saved passwords) but the risk assessment is your own.

Being fair that guide does later say in a red box quote:Note: This assumes you will run as the user radarr and group media. You may change this to fit your usecase. It's important to choose these correctly to avoid permission issues with your media files. We suggest you keep at least the group name identical between your download client(s) and Radarr. Which does make the warning about permission issues. Ah, permissions, the gift that keeps on stinking.

UNIX permissions are super simple, try proper ACLs if you want stink. The guy posted how his Radarr service looks in his very first post asking about this:Dead Goon posted:
It should be easy to decipher that the service will run as user radarr and group radarr by default. What the -data option does you would have to look at documentation to be sure, but given that it's pointing to a path under /var/lib, a good guess would be that it's used for storing program state. That means it needs to be writable for the service process. Technically and security wise it would be nicer to set up fitting group and adding yourself and radarr to it, running the service as system user radarr instead of giving the software full access to everything your login user account can do when the only thing you need is to be able to access the data it spits out to disk, but I know most people just don't care enough to do this at home.

But also, the security risk is that Radarr has bugs or is straight-up bad software that will delete your files. This has nothing to do with other potential users on a time-share machine.

Dead Goon posted:As it's finally running I shall leave as is for now, but knowing a little more about what I need to be doing I will have a look at doing it properly in the future. Keep this in mind because this is how a *lot* of linux services work: they make a new limited user to run themselves as, and rely on group permissions to gain access to files. This can get a bit complicated to keep track of because you now have a bunch of groups. And a folder can only be owned by one group, nor can you have a group in a group. So radarr by default does the radarr:media, and you're supposed to just change the group on home/myuser/Videos or whatever to myuser:media, with r/w given to the group. That way you have ownership and both you and radarr (and anyone else in media) has full access. But radarr can't see anything else in your home folder. But maybe you also have a sambashare group controlling access to folders you're sharing to the network, and you want to share ~/Videos. At that point you can add the network users from samba to media group, or radarr to sambashare. Start taking notes when you have more than 3 or 4 of these types of interactions.
