Okay, the first bootstrap was a success. I'm tweaking specfiles to get system packages built earlier in the process, as well as updating the first set of binaries for you people out there who are restless.
kdegraphics has a missing link dependency on lcms, either install lcms, or rebuild kdegraphics. Will make a fresh build.
For now I'll see if I can put a fuser -k on the tempdir in catalyst, ought to solve the umount problem due to lingering gconf process'.
Update:
okay, gcc update was a minor one (pfhew ;) , and I got the stray-process killing patched in (wee) . Doing a rebuild again to see if I can get kdegraphics to link properly. Other than that, I'm starting to become satisfied with this. :)
