I have the unique pleasure of waiting as /usr is copied back to my Ubuntu SSD after offloading it to a sea of spinning rust to save some space. Surprise surprise Ubuntu keeps almost everything in /usr these days and it didnt boot :l but hey, at least BusyBox in initramfs has my back for times like these. Can i mount a specific ext4 directory with options? the issue seems to be my attempt at using a bind mount fails while running from the ramdisk, for whatever reason it wont mount my large data drive on /data
I’m not too familiar with Ubuntu, but the arch wiki has a section about moving /usr to a separate partition: https://wiki.archlinux.org/title/Mkinitcpio#/usr_as_a_separate_partition
Maybe using these instructions, you can still offload /usr to a mechanical drive.
Just out of curiosity, how large is your /usr directory? Mine is only 30GiB (arch Linux, kde plasma with all apps + hyprland), which only takes up 17GiB on my disk due to btrfs compression (zstd level 15).
Ohh I like the sound of that compression ratio, I’ll have to look into it. I’m just using ext4, plus I should repartition the whole disk I’m throwing away another 50Gb keeping my home partition on the SSD…
My /usr is 35Gb but I’m squeezing Ubuntu into a 50Gb partition and between docker, snapd, postgres, apt, and Minecraft it’s hitting 100% weekly.
Im pretty sure it would be fine if i was trying to dedicate a whole partition to /usr, maybe that’s the right answer after all
