install into directory (no 'part', no 'logvol', etc.)

[philfry]

Hi,

I was wondering whether or not it would be possible with anaconda/kickstart to install into an already mounted directory tree instead of using part, logvol, etc.

My intention is to do the disk setup in %pre, for example:

%pre
rpm -ivh --nodeps \
  https://myserver/kmod-zfs-$(uname -r)-${zfsver}.x86_64.rpm \
  https://myserver/zfs-static-${zfsver}.x86_64.rpm
modprobe -v zfs
udevadm control -R
zpool create -m none rpool /dev/sda
zfs create …
# and so on
%end

then mount the zfs tree in /mnt/syssomething and let anaconda use this root for installation, in order to get a root-on-zfs machine.
Yet, anaconda complains about an incomplete kickstart, when not having set at least a part for /. Which is not possible for zfs right now.

Is there any workaround or tweak for that?

never mind, found it: inst.dirinstall=/mnt/sysimage is it.
