Nevermind, I missed that there was an ongoing effort to fix the out of
memory bug. And the thing I'm proposing here wouldn't even work. Marking
this as invalid and a duplicate, sorry about that.

** Changed in: initramfs-tools (Ubuntu)
       Status: New => Invalid

   Can't boot: "error: out of memory." immediately after the grub menu

Title:
  Set MODULES=dep by default in new installations?

Status in initramfs-tools package in Ubuntu:
  Invalid

Bug description:
  Multiple users have recently been reporting strange "out of memory"
  errors during early boot. Most notably, the Kubuntu Focus NX system
  seems to be unable to boot when the proprietary NVIDIA drivers are
  installed for an external NVIDIA GPU. These errors seem to be the
  result of an overloaded initramfs file. I currently don't know why
  overly large initramfs files cause an out-of-memory error, but they
  do.

  In all cases I have seen, the problem was resolved by editing
  /etc/initramfs-tools/initramfs.conf, changing the line "MODULES=most"
  to "MODULES=dep", then regenerating the system's initramfs files. This
  results in no more out-of-memory errors, and in at least one case, it
  may have contributed to faster bootup speeds. I have not yet
  encountered a system that doesn't work when this setting is changed.

  It might be too late in the Lunar cycle to experiment with this, but
  in my opinion, it might be a good idea to eventually start testing the
  effects of this setting on many systems by enabling it by default in
  new daily images and seeing what happens on our testers' systems. This
  may enable Ubuntu to work on more hardware, and increase boot speeds,
  which I think are both good things.

  Obviously, this comes with the risk of causing some systems to become
  unbootable, as the failure to include the correct modules could cause
  problems. Since we are close to the Feature Freeze for Lunar, I think
  we should probably not try it this cycle, as I would expect it to take
  more than three months to properly test. But perhaps for 23.10, we can
  enable this close to the beginning of the cycle and see what happens?

  EDIT: The Kubuntu Focus team has already set the MODULES=dep option
  for the Kubuntu Focus NX systems by default, and also changed the
  compression algorithm used by default. The system's boot speeds
  increased, and there were no more out-of-memory errors after
  installing the NVIDIA drivers.
