enable build for ocaml bytecode
by Olaf Hering
This is a first attempt to build libguestfs with just a ocaml bytecode
compiler. The three tools written in ocaml will be build only when an
ocamlopt compiler is available.

[PATCH] sysprep: handle distro specific sysv scripts
by Olaf Hering
Currently firstboot would only work on redhat-based images.
Handle redhat-based, suse-based and debian guests, error out in case of an
unknown distro.
Update firstboot.sh:
- make sure scripts exists and can be executed
- add LSB header to avoid insserv warnings later on
- run script only if called with "start"
Update functions, pass only required options.

This first factors out all the partition sizing, and then resizes the

limitation with btrfs:
mkfs_btrfs: /dev/vda2: device /dev/vda2 is too small (must be at least

[PATCH] handle --use-installed in zypp driver
by Olaf Hering
An attempt to use installed files in zypp driver.
Add also a comment about the theory of operation.
Enable set -x in shell only in verbose mode.
This adds a dependency to xmlstarlet, which is required to parse zypper output.

So I peppered some fprintfs in launch-appliance.c to try and narrow
down the problem. Just below the comment:
* does not mean the daemon is up until we read the
* GUESTFS_LAUNCH_FLAG below. Failures in qemu startup can still
Is the call where it fails:
r = guestfs___recv_from_daemon (g, &size, &buf);
r is -1 and size is zero
How can I debug this problem further?
I suppose I could build/debug the qemu side of this process...
