question about maintaining /boot

edited Jan 19, 2024 1:08AM in Linux Operating System (MOSC) 2 commentsAnswered

We have a mix of OL7 and OL8 and now looking to get up to speed on OL9. An ongoing issue is the maintenance of /boot which we find we have to manually free up space by using yum remove to remove old kernels before we can get them updated. It just seems like there must be a better way to manage this so wondering what I'm missing (aside from a better understanding of the boot process).

We are almost exclusively using the UEK kernel and I think things have changed a bit from rel 7 to rel 8 like for example the RHEL kernel used to work properly with the "installonly_limit=2" entry in the /etc/yum.conf file but I don't think uek uses that and I have a note that says the 'yum update kernel-uek' cmd will install the new kernel and remove the old one.

Howdy, Stranger!
