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.

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.
