Hi John,

you can use a hook for that, before task partition is called. First use
fai-mount-disk -f
for mounting the local disk according to the fstab. Then check if
there are files in $target/home. If files are found, stop the
installation, otherwise call fai-mount-disk -u to umount the local
file systems and go on with the installation.


Wow, I didn't know about fai-mount-disk. I can think of all kinds of things to do with that. For example, you could mount / and copy off the ssh keys before the install.

Thats a nice utility. For years I've been pondering this kind of problem and always figured that it was too much work to figure out how to mount the disks before the install. I guess you guys think of everything.
