[20:30] Eickmeyer: I just did an install test of Ubuntu Studio focal.5, manual partitioning, with /boot on ext4 and root on btrfs. The swapfile dependency is failing, probably because of copy-on-write. Is this expected? [20:31] arraybolt3: That's possible. btrfs was never a supported test case for Focal, especially without a dedicated swap partition. [20:32] I guess I'll do it with Ubuntu Studio focal.4 and see what happens (hopefully it will fail there too). [20:33] The system still boots and works just fine, so 👍️ just no swap (and modern Ubuntu Studio doesn't even make a swap so who cares) [20:34] Yeah, I'm not even sure why Studio doesn't make a swap file without a partition. Does Lubuntu? [20:34] Lubuntu does make a 512 MB swapfile, and gives an options to either create or skip creating that swapfile. Ubuntu Studio does not offer such an option and just skips swap. (On 22.04) [20:35] (On Lubuntu Focal, Lubuntu doesn't make a swapfile at all.) [20:35] That might need to get fixed. [20:35] In Jammy/Kinetic? [20:35] Yes. [20:36] I remember saying something about it before, but I believe we decided to say "it's not a bug it's a feature" since having a swapfile on Ubuntu Studio could result in xruns during music recording. [20:37] It can, for sure, but if you have enough RAM that's not a big deal. [20:37] Right, but if you have enough RAM then you don't need swap. [20:37] One can always run "swapoff" and be set. [20:37] I figure better to have it configured for good music recording OOTB rather than rely on the user knowing how to run swapoff. [20:37] I thought it was because I had 64GB of ram it just wasn't making one. [20:37] Nope, just default. [20:38] But if a user has a system that benefits from a swapfile, that's probably a good indicator that their system isn't powerful enough to use Ubuntu Studio properly. [20:38] Honestly, we haven't had any complaints. [20:38] (I mean, I guess if someone only did art on the system then it might need a swapfile yet benefit from Studio, but Studio is usually geared towards audio AFAICT.) [20:39] I'll regression check just because that's how point releases work, but I don't see any need to change anything swap-related in modern Ubuntu Studio. [20:40] arraybolt3[m]: Usually, but we do want a well-rounded system for audio, video, graphics, and photography. [20:41] Meh, I guess that makes sense. Really you're the team lead. Maybe we can figure out how to make it say "Make swapfile (for graphics and art on lower-end hardware)" and "No swap (for audio on higher end hardware)"? [20:43] One OOM can ruin your whole day if the kernel decides the app to remove from memeory is the project you have not saved yet... or even the DE [20:44] * OvenWerks has had that happen [20:47] Eickmeyer[m]: I had not noticed swap not being added because I do manual partitions and add swap if I want it... or in most cases there are a few swap partitions already hanging around which the kernel tends to just grab. [20:47] OvenWerks: As it should. I'm very surprised that nobody has raised any issues related to memory. [20:48] now that it is mentioned, my fstab does not have a swap listed... htop shows one in use anyway. [20:50] another related thing is that the install really wanted me to create a boot partition but did not complain about no swap. I declined the boot partition creation anyway :) [20:52] * OvenWerks doesn't know how long he will continue to get away with that... maybe till he gets another MB [20:52] OvenWerks: You should just be able to point it to the EFI partition... it needs that for UEFI boot, but it won't format it. [20:53] It's mostly just to set it up for fstab. [20:53] just one partition for 22.04 [21:04] To be fair, I was booting to 20.04 as default and didn't want to mess that up. When I switched to booting to 22.04 by default I just did a grub-install. [23:24] Alright, regression tested swap failure on 20.04.5 when root is on btrfs - it is not a regression.
