I was experimenting with mic just a moment ago. I used ks file with
prepackages and, of course, I got into trouble (notice the lib;527bba47
link below)

The invalid link comes from a failed instalation of the filesystem
package.

INFO: Installing: filesystem                                              [

Although removal of the prepackages from meta-mobila package and the ks
file helps (as Jacek reports) and the filesystem package is instaled
before any other package tries to install something in /lib or other
directories provided by the filesystem package as links,

we still have no guarantee this won't break in the future. What we've
got is a kind of a race condition. We need to *force* the filesytem
package to be installed as the very first. Would renaming the rpm to
something like aaa_filesystem help?
