With a large update to be made, eg. the 900 package one I questioned yesterday, are there any suggestions to avoid possible complications?
Two examples, I'd like to know of others too:
I'm not running the most recently installed kernel, I assume I should reboot to that.
I normally have a graphical environment running. Would it be better to: a) shutdown X and update from a straight CLI environment b) logout from the GUI and update from a vt CLI c) update from a GUI login as root or d) doesn't matter, do as normal -- from an ssh login, "sudo yum update"?
...
In such scenario (xxx packages to update) I normally split the update command into
# yum clean all # yum update glibc* rpm* yum* # yum update # reboot
The update to glibc*, wouldn't that replace the current versions on disk? If so, wouldn't there be a problem if one had to reboot before the yum update could run or complete.
Theoretically this wouldn't be a problem, as execution of next yum command after installation of new yum and glibc will load new image of glibc into RAM, and will be happy, but other stuff that still runs may not (as they will be expecting to use old glibc image). So, last but one line before reboot in his script has no reason to fail. I'm sure this is his production script or sequence of commands, so he experimentally confirms the above.
Just my $0.02

Or do applications not need specific glibc versions but only version X or newer.
