[CentOS] 5.0->5.1 upgrade problems SOLVED (kindof)

Hi, 

I finally solved my update problems by using rpm command. I found that I
had 2 versions of e2fsprogs installed, one ending with EL4. Don't know
where this came from, because there was never a EL4 on this machine. But
when I removed it, yum update run fine.

Thanks, Andreas
