CentOS - Apr 2007 - Update Centos-4.4 to centos-5 spents a lot of time in "restorecon"

Hi,

having running centOS-4.4 on a really fast machine (16 GB memory, 8 Opteron
CPU's, SATA drives).
Then making an update  by using the Centos-5 CD's. The start was fast, but
during update,
the installer spents a very, very long wallclock time during selinx updating:
for about 1/2 hour
the updater runs in a restorecon/find sequence.

And at the end, before the MBR is written, it spents again a long time in
"install".

Can somebody explain this?

Regards

Did the upgrade eventually finish ok?

As the SELinux model (and policies) seem to have changed pretty much
between 4.4 and 5, I'm not really astonished by this relabeling.

What do you mean "in install"?

Cheers,
