This is an experimental rebuild of libguestfs with the supermin appliance:
http://koji.fedoraproject.org/koji/taskinfo?taskID=1418138
Make sure you install libguestfs >= 1.0.48-2. Earlier versions were broken in various different ways.
I've tested it locally on i586 & x86-64 and it seems to work for me.
You'll get warning messages like this:
<fs> alloc /tmp/test.img 10M <fs> run
cpio: ./usr/sbin/glibc_post_upgrade.i686: Cannot open: Permission denied cpio: ./usr/sbin/groupadd: Cannot open: Permission denied cpio: ./usr/sbin/groupdel: Cannot open: Permission denied cpio: ./usr/sbin/groupmems: Cannot open: Permission denied cpio: ./usr/sbin/groupmod: Cannot open: Permission denied cpio: ./usr/sbin/tzdata-update: Cannot open: Permission denied [etc.]
This is a known problem (it tries to pull some files from the host filesystem which are not readable) and shouldn't affect any operations and it still passes the test suite even without those programs.
