Public bug reported:
When booting a kernel with overlayfs build-in, ie not as a module, booting
incorrectly errors out with:
/cow format specified as 'overlay' and no support found
This turns out to be a false-positive since, in scripts/casper we have:
modprobe "${MP_QUIET}" -b overlay || panic "/cow format specified as
'overlay' and no support found"
This was added previously when there was an out-of-tree overlay
filesystem, now deprecated by the in-tree overlayfs.
The correct fix is to change the line to:
modprobe "${MP_QUIET}" -b overlay
If there is no overlayfs support, the later 'mount' command will fail.
