indeed, specifically, did those issues with the broken kernel update get sorted out?
I dunno about any kernel issues on mirrors or syncing or whatever...
After a quick backup set check, I bit the bullet on one of our main CentOS 4.6 i386 production boxes and did a full update to CentOS 4.7 i386 yet excluding the kernel* update in the /etc/yum.conf
Reboot and after quick check, it appears there are no noticeable issues.
As a side note, this particular box started about as an original CentOS4 approx 4 years ago and has been updated many times without one issue.
Again, good work CentOS team and supporters!
