(more fun and games from kernel land.)

  i just built a new kernel, installed modules, tossed the kernel
into /boot, etc. etc -- the regular stuff.  then edited /etc/grub.conf
and added a new stanza for the new kernel, almost identical to the
old stanza, but not "initrd.img" line.

  the new grub.conf file, with a second vmlinuz stanza:

...
title Red Hat Linux (2.4.18-14)
        root (hd0,7)
        kernel /vmlinuz-2.4.18-14 ro root=LABEL=/ hdb=ide-scsi
        initrd /initrd-2.4.18-14.img
title Red Hat Linux (2.4.20-2.2)
        root (hd0,7)
        kernel /vmlinuz-2.4.20-zaurus ro root=LABEL=/ hdb=ide-scsi

most of the above was just cut and paste, and the original 2.4.18-14
kernel has booted nicely all this time.

  booting the new kernel failed, allegedly couldn't mount the
root FS "LABEL=/", as if it wasn't capable of translating the fact
that i was referring to /dev/hda1 by LABEL and not device name.

  i rebooted and, at the grub menu, just edited that line to say
"root=/dev/hda1".  no problem.

  what was *that* all about?  is there some kernel config option
i might have inadvertantly turned off that allows a grub line to
say "root=LABEL=/", rather than "root=/dev/hda1"??  i'm puzzled
by this one.
