[CentOS] Hosed by 4.2

[Joe Landman]

FWIW:

   A yum upgrade on my main server (no pre-loading kernel, yum, etc), 
caused a hiccup.  I didn't see the x86_64 release notes until too late. 
  I did see the useradd chomping down CPU time.  I ignored it as long as 
possible, but then the install wound up hanging the machine.  Rebooted, 
and had to do some fancy tweaking using yum to restore the system to a 
stable state.  Not difficult, just a minor annoyance.

   I am not sure if others are having issues with the 4.2 upgrade, but 
it might be a good idea to avoid upgrading the package (I think it was 
mysql) to avoid hitting that.

   That said, apart from a missing firewire driver, I am quite happy 
with Centos (and that is an upstream provider issue, addressed for the 
most part in centosplus).  The minor pain I went through with this is 
nothing compared to the days of sheer abject terror I went through using 
other distributions "upgrade" system.

   Good work folks!
