installer does not parse /etc/fstab file correctly during an upgrade: 1. line which starts with a '#' does not get ingnored 2. there was an attempt to mount /dev/fd0 on /mnt/floppy just because it was entered in my /etc/fstab as ext2 filesystem. 3. there was an attempt to mount /dev/hda1 on /NT as ntfs !!!! 1 and 3 cause a catastrophic failure, 2 just an error box.
Should be fixed in latest release.
