Just had a rather odd experience with the FC3 install messing up the grub that i told it not to touch! sda1 has Scientific Linux (a RHEL3 derivative) sda2 had FC3-test3, using grub from sda1 (I installed FC3-test3 without grub, and later manually configured grub to also boot from sda2) I decided to do a full fresh install, like i had installed fc3-test3. Identical procedure. I tried to boot the old SL/RHEL3 from sda1.... get a kernel panic, with the "no init found" message. So, somehow the FC3 install messed up the MBR/grub info.... I then tried rescue boot and changing all LABEL=/ (and similar) to the hardcoded /dev/sdaX references and even re-ran grub-install, but to no avail. Anybody have a clue what could be going on here. From running chroot in the rescue cd it looks like all the proper files are in my /boot, so I'm quite stumped here. - peter
