it concatenates the boot= entry with what is in /var/lib/lrpkg/root.mount
and then iterates through the list trying to mount that device, probably being unable
to mount /dev/sda1 and skipping to the next available device.
If there is a floppy it will mount it and be happy.
rc=1
for d in ${DEVICE}; do
for t in ${FSTYPE}; do
if qt mount -r -t $t /dev/$d $MNT ; then
echo
[ "$VERBOSE" ] && echo "Mounted /dev/$d as $t"
qt ln -sf /dev/$d /dev/boot
echo $t>/var/lib/lrpkg/boot.fstype
echo "$INITRD=-t $t /dev/$d">/var/lib/lrpkg/backdisk
<XXX>
this is probably where the /dev/fd0 for initrd comes from
</XXX
echo "/dev/$d $t" >$PFX/pkgpath.disks
rc=0
break
fi
[ $rc -eq 0 ] && break
done
[ $rc -eq 0 ] && break
done
I would still recommend to try detecting the availability of the device instead of
just delaying.
