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 would think you could put /usr on a separate disk just fine, as long as it was available to mount at boot time.
How small is your SSD that you’re trying weird stuff to save space? Even in the tens of gigs should be enough to run Ubuntu. I just checked two full desktop systems, and they are 32 and 24 GB used for the root partition.
I’m just irresponsible with installing software on my desktop machine. It’s a 50g partition but I use it for music, software development, and some games (looking at you flightgear) which eventually add up. I’ve been slowly moving pieces of the setup onto a 3tb rust gyroscope with mostly success. Luckily this blunder was recoverable and I’m back to where I was before

Interestingly, when I added the bind mount to /usr the init environment failed when trying to set up the actual root fs because it was trying to bind mount from the init ramdisk filesystem paths into the new root path. im sure I could cloodge together a script to patch things up in the initrd but my days of straying from a sane upgrade path on Ubuntu are over (now I just do that on nixos because I don’t know what I’m doing)
