You can only run 1 kernel at a time, but if you I guess what you meant correctly, then yes, your old kernel won't be gone. It will still show up in LILO or Grup (mine shows up as Linux Bak, Linux Bak1, etc in LILO) > So once I reboot > by default it will load the newest kernel?

The only thing you need to worry is that if you fail to boot, than you have no way to tell the machine to use the old kernel without the machine physically in front of you. But if there's someone you can call that has physical access to the machine, you can always tell him/her "Hey, watch the LILO (or GRUB) and choose the old kernel when booting! " :) FWIW, I have always upgraded my kernel when newer version available using Redhat up2date, and never had any problems. I also run Apache, MySql, PostgreSQL, Oracle (no, not all on the same machine), PHP, and a bunch of other stuffs. But, as always the disclaimer, YMMV. RDB -- Reuben D.
