Using beta1 pcmcia.img to FTP install against ftp.beta.redhat.com on
Prostar 8680 laptop.  Upgrade from RH 6.1.  lilo.conf before upgrade 
included normal 2.2.12-20 stanza with label=linux, 2 2.3.x stanzas with 
labels of their kernel version, and other=/dev/hda1, label=win98

lilo.conf gets rewritten, but lilo itself either doesn't get run or (much 
more likely) fails to run successfully.  The in-place lilo.conf already 
had an other=/dev/hda1 with label="win98".  During the upgrade process it 
defaulted to "dos" as the label to give hda1, but I renamed it to win98.  
Apparently it didn't catch that a stanza was already in place with that 
label, and most likely lilo failed with the same message it failed with 
when I booted (into 2.2.12-20, the kernel from before the upgrade) and re-
ran lilo to attempt to boot into the 2.2.14-100 kernel instead:

Fatal: Duplicate label "win98"

Fix will most likely involve duplicating the logic added (during 6.2beta 
iirc) to not repeat label=linux stanzas, I'd imagine.
