[Morphix-devel] minimodule overlayfs

[Rene C. <re...@dc...>]

Gday,

Ive got minimodules overlaying with the mainmodule using unionfs. Ive
only began testing this, but so far its looking good. At the moment the
code only supports unionfs as the overlayfs.

Here is a run down on things.

o minimods have a new file (/morphix/mini_module.conf) which contains
certain bash variables. One variable im using for the overlayfs is

MINI_MODULE_OVERLAY=1

/morphix/mini_module.conf isnt mandatory.

o /etc/init.d/morphix-start mounts minimods, but doesnt execute
/morphix/loadmod.sh. This enables the initial unionfs mount command to
include the mounted module within the first `mount -t unionfs -o dirs` command.

o /morphix/loadmod.sh is then executed by /etc/init.d/load-minimodules.sh.

Ive tried adding the unionfs branch with unionctl, though unionctl doesnt
seem to allow rw unions with ro branches.

If anyone has any objections or comments please speak up. Ill cvs commit
this in within the next couple of days.

Cheers.
