Grub question
Here's what I assume to be a simple grub question On one of my systems, /boot is getting quite full with all the kernel updates and I'd like to delete most of the old ones, keeping a couple of the most recent ones. Does one then need to delete the corresponding lines for the deleted kernels in grub.conf? Does anything have to be done after that so grub is aware, like one had to do with the old lilo.conf, i.e., run lilo after any changes that were made? Thanks! - Larry -- P.

Re: Grub question
Larry, You can just delete the entries from grub.conf, no commands need to be run after that. You also might be interested in the installonlyn (I think that is the name) yum plugin. It lets you limit how many old kernels to keep installed. Cheers, Mark P.

Thanks! - Larry It's been my experience that the entries in grub.conf get automatically removed as long as you use rpm (or yum) to remove the old kernels. I don't know at what release this started, but it has been true for a long time now. -- -- Jeffrey Anderson| [EMAIL PROTECTED] Lawrence Berkeley National Laboratory | Office: 50A-5104E | Mailstop 50A-5101 Phone: 510 486-4208 | Fax: 510 486-6808

They are used for the threading. I always thought threads keyed off the subject line, That would be much too simple. and I've been using email since it was invented back in the 70's.
