Comment 7 for bug 1382364

Sorry for inactivity.
When we have on ceph-osd more than 23 partitions, installation of ubuntu fails.

How to reproduce:
1. Configure 30+ partitions for ceph-osd and 30+ for journal on the same disk(just to be sure).
2. Start installation and wait until installation finish.
3. Ubuntu installs boot-sector and goes to reboot the machine.

What expected:
1. Installation is finished.

What we really have:
1. Node goes to reboot, but after reboot installation starts again because preseed was corrupted in post-install section.
