Package: live-boot
Version: 3.0~a24-1
Dear Colleagues,
I just had to fight with live-boot and overlayfs on Ubuntu Precise.
The Ubuntu Precise Kernel doesn't support the aufs module anymore, but
as a replacement it supports the overlayfs module.
Sadly, live-boot doesn't support overlayfs correctly.
overlayfs doesn't support the dirs=<dir1>=<rw|ro>:<dir2>=<rw|ro> mount
option. So, mounting overlayfs fails.
I tried to fix it for me, and found this solution: (Patch against latest
git head rev)
sadig@t420-sadig:~/live-boot/live-boot$ git diff -p -u
diff --git a/scripts/live b/scripts/live
index 8ffbc20..12d99bd 100755

This works for me. Eventually it's also the correct way of using
overlayfs inside live-boot.
As I'm trying to get FAI running on Ubuntu, this works now as expected.
Sadly I'm not able to test anything else then this FAI usecase.
I tested it with using a nfs mount as live filesystem and a squashfs
image. Both ways are working with the mentioned patch.
There is the RFC page http://live.debian.net/devel/rfc/overlayfs/ , but
sadly the patch which was posted on paste.debian.net is gone.
Hope it helps,
