The most sustainable solution is to increase your /boot filesystem,
which unfortunately might not be convenient.

MODULES=dep should be fine as long as you do not intend to move your

It would be possible to create the initramfs in another directory, but
to ensure atomic upgrades it would have to be copied to /boot anyway
_before_ unlinking the old one (if any). Otherwise the system could
become unbootable if it crashes at the wrong moment.
