Me I'm slow to accept the theory of a Red Hat patch because root=LABEL=/ does work when I build kernel.org source almost as is. I only add a .config from Red Hat, and I build in a Red Hat Linux. I have not yet modified my copy of the kernel.org source in any other way. > Sanity check ... Sanity check ... Sanity check ... Thanks for finding the time to ask. To my newbie eye, all these checks pass, I'm curious to know if you agree. Specifically I see: > IIRC each menu section must end > in `boot' command ... The string "boot" appears in three lines, but never as a command. I quote: $ sudo grep -i boot /boot/grub/grub.conf # NOTICE: You have a /boot partition. This means that # all kernel and initrd paths are relative to /boot/, eg. #boot=/dev/hda $ > Sanity check: Are you _really_ using it? > When you get the grub boot menu, > press `e' and inspect what grub is about to execute. Diff by eye says same. Pressing e to edit the kernel line and later b to try the edited lines panics if "root=LABEL=/" and works if "root=/dev/hda2". > Sanity check: Is what you wrote the whole and > unmodified content of your grub.conf? At first I posted the supposedly relevant fragments. The full glory of 76 lines now appears below. Play proceeds independently of this thread, so the timestamped snapshot you see here doesn't byte for byte match the undated context for the fragments you saw before. > Sanity check: grub.conf? My grub definitely calls it > menu.lst See the tty log below. I use find -printf in place of ls -l to fit within the 54 column limit of the path to you thru which this post will pass. $ date Tue Jun 24 10:22:59 MDT 2003 $ $ find /etc/grub.conf -printf '%p ->\n%l\n' /etc/grub.conf -> ../boot/grub/grub.conf $ $ find /boot/grub/menu.lst -printf '%p ->\n%l\n' /boot/grub/menu.lst -> ./grub.conf $ $ sudo cat /boot/grub/grub.conf | wc 76 282 2422 $ $ sudo cat /boot/grub/grub.conf | sed 's/-[a-oq-z][a-z][a-z]/-xyz/' # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition.
