I tried to get live-boot to work with
<jessie>
linux-image-3.18.0-trunk-amd64
live-boot{,-initramfs-tools}/experimental (5.0~a1-1)
The first problem I hit was in 9990-overlay.sh:
if ! cut -f2 /proc/filesystems | grep -q "^${UNIONTYPE}\$"
then
panic "${UNIONTYPE} not available."
fi
modprobe -q -b ${UNIONTYPE}
The file overlay.ko was in the ramdisk,
but the module wasn't mention in /proc/filesystems.
I kludged that with
echo overlay >>/etc/initramfs-tools/modules
The second problem I hit was in 9990-misc-helpers.sh:
unionmountopts="-o noatime,lowerdir=${unionro},upperdir=${unionrw}"
mount -t ${UNIONTYPE} ${unionmountopts} ${UNIONTYPE} "${unionmountpoint}"
I got dumped into a panic shell.
When I run the above mount by hand, I get
overlayfs: missing upperdir or lowerdir or workdir
Per https://www.kernel.org/doc/Documentation/filesystems/overlayfs.txt
| At mount time, the two directories given as mount options "lowerdir" and
| "upperdir" are combined into a merged directory:
|
| mount -t overlay overlay -olowerdir=/lower,upperdir=/upper,\
| workdir=/work /merged
|
| The "workdir" needs to be an empty directory on the same filesystem
| as upperdir.
I haven't fixed this, and I'm out of time today.
I hope this helps.
