Overlayfs #1

Closed mibodhi closed 9 years ago

Hi Davide!

I'tried to follow your example for initramfs script (init-bottom). There was a syntax change in mounting rw rootfs on top of the ro rootfs in recent overlay fs. Still trying to adapt this script. Wonder if you have plan to do that?

Thx, bodhi

Hi Bodhi,

which kernel version are you working this on ? still 3.xx or 4.x already? Last time I tried it was on kernel 3.14, and I had to merge overlayfs tree from mszeredi's. I've sent you my skype contact to discuss it faster.

Hi Davide,

I'm using kernel 4.0 (http://forum.doozan.com/read.php?2,12096). And the overlay package is from mainline Debian.

I've just tested this new syntax mods to your script, and it works fine:

ROOT_RW_ROOT=/mnt/root-rw/rootfs ROOT_RW_WORK=/mnt/root-rw/work

MOUNT_PARMS="-t overlay -o lowerdir=${ROOT_RO},upperdir=${ROOT_RW_ROOT},workdir=${ROOT_RW_WORK} overlay ${rootmnt}"

Please feel free to adapt this to your script, when you have time.

Thanks for an excellent script! it saved me countless hours researching this :) -bodhi
