[CentOS] 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?
