I take it then that there is still no way to grab the driver
by controller:deviceid? I'd rather have scsi/ have devices
of the type scsi/[a-d][1-7][1-40?] then devices that get changed
often. I also like the way extended mapping was proposed
for bsd extended/slices. A nice group of 10/extended type
should take us 15 or so months of os development. Plus
a nice absolute method of mapping drives makes for setting
the system up nicer, independent of what else happens to
be in the machine at the time. Also, has proc/scsi
been working in the newer kernels? I was going to
write a short shell script to link the volume labels
to the absolute devices (but then my system died)
so I havn't had the time (or machine) to run bleeding edge
kernels lately. I also heard rumors of treating a continous
series of blocks as a partition, for instance making
windows swapfile also be the linux swappartition (not file)
because windows has to have its partition as a contigous
file. Better then making a 32 meg dos partition with a
windows/linux swap file on it. (added filesystem overhead)
Oh well, just what I was thinking about the current methods.
