Package: initramfs-tools Version: 0.92o Severity: normal Tags: patch Hi. I'm trying to get something like LiveFlash working with btrfs as root filesystem. Currently debian versions of blkid(8) and other e2fsprogs binaries don't recognize it. According to initramfs-tools(8) it's possible to specify filesystem type manually at boot time using "rootfstype=my_fs" parameter.
Current version of initramfs-tools waits for root device to appear and
checks that filesystem type can be detected:
while [ ! -e "${ROOT}" ] \
|| ! $(get_fstype "${ROOT}" >/dev/null); do
/bin/sleep 0.1
slumber=$(( ${slumber} - 1 ))
[ ${slumber} -gt 0 ] || break
done
But get_fstype don't understand btrfs, so it just waits for timeout here.
My problem is that ROOTFSTYPE is used only _after_ this loop and there is
no way to workaround it.
I think that we should allow get_fstype to fail if filesystem type was
provided manually at boot time. We can just check something like [ -z
"${ROOTFSTYPE}" ].
Please take a look to attached patch as a reference fix.
Thanks
