Errata updates for RHEL

[George Magklaras]

For the 5.2 box, after the RHN registration, you can do (as root) a:

yum -y update

This will perform all the necessary updates and will essentially resolve 
dependencies without intervention provided that your network connection 
is fairly reliable and that you have enough space on /var, /usr to get 
those updates (usually not a problem).


For the 4.1 box, judging from the number of updates you need, if I were 
you, I would:

i)Backup everything up on portable drives (system partitions: /, /etc/ 
,/usr/ /var/ and other) and

ii)Download the latest media from your RHN subscription channel 
(Software Download section)

iii)Re-install the OS from the new media.

iv)Keep the backup handy in case the box came with other apps that are 
non RH specific and restore the non-standard bits and bobs.
