It apparently fixes the issue.  However, the simpler solution is to reverse 
the libselinux update:
apt-get install libselinux=1.19.3-1_1.rhfc2.at \
     libselinux-devel=1.19.3-1_1.rhfc2.at

The issue does exist on FC3, but on FC3, I get two error messages from glibc 
about an invalid pointer being freed and it does not cause a segmentation 
fault in init.  BTW, I have a second FC2 box (my mythfrontend) that does not 
exhibit the behaviour above and still boots with the latest updates.  I 
don't know what the difference is between those boxes.

Kind regards,

Mark
