v2.3.2

v2.3.2 — RAM-mode /boot space preflight check

dracut -f writes the rebuilt initramfs to a .tmp file next to the
existing one for that kernel before renaming over it, so /boot briefly
needs room for both at once, not just the new image. Ported from the
x86 sibling fix after a user (hd3291) hit a raw "No space left on
device" from zstd there (same module, same bug).

Module 14 now checks free /boot space against the current initramfs
size before every dracut -f call (overlay enable and disable paths)
and fails with an actionable message — free up a kernel, or use
Strategy V (volatile), which needs no dracut rebuild at all.

Ported from the x86 sibling after a report by hd3291.
