So here is a 1.24.X version which appears to work, at least for the
bytecode case.
OK, I'll need to rebase this because the upstream code has changed a bit.
Two random thoughts:
(1) This morning I discovered it's possible to make automake compile
OCaml programs, provided they contain at least one C object (which all
of ours do):
https://github.com/libguestfs/supermin/blob/master/src/Makefile.am#L94
It needs a relatively small hack to add -l options in the right place:
https://github.com/libguestfs/supermin/blob/master/src/supermin-link.sh.in
(2) Related to the above, I rewrote supermin. This entailed dropping
the zypper/SUSE support *temporarily*. I intend to add it back. It
should in fact be simpler, as the Fedora support just uses 'rpm':
https://github.com/libguestfs/supermin/blob/master/src/rpm.ml
and it seems likely that any RPM based distro could use the same code
(ie. SUSE support won't need to depend on zypper at all).
Except for one small point: we need a tool to download RPMs from the
repository, for which I'm using yumdownloader in that file. So that
will need fixing for SUSE.
