I have switched to devfs on birdseye, but found problems, mainly
directories and devices not appearing.

The system is Linux 2.4.0-test9, glibc 2.1.1, util-linux 2.10p.

There is no /dev/floppy after I modprobe floppy, and no /dev/ide/fd.

There is no /dev/loop after I modeprobe loop.

I have two SCSI adapters, and use lilo to pass the parameters of one
of them to the kernel.  This is always scsi0.  But in clueless hope
I have tried giving the kernel "scsihosts=aha152x:aic7xxx" anyway.

scsi0:0:0 is a tape drive.  scsi0:4:0 is a CD burner.

scsi1:0:1:0, scsi1:0:2:0 and scsi1:0:4:0 are hard disk drives.  There
are no problems with the diskoi (phew).

If I try to list /dev/tapes/ the st.o module is loaded and prints a
message, but the directory doesn't appear, and the device file doesn't
appear under /dev/scsi.

There is no /dev/sg directory after I modprobe sg.

There is a full directory tree under /dev/scsi/host0, but the lun
directories are uninhabited:

host0:
bus0/

host0/bus0:
target0/, target4/

host0/bus0/target0:
lun0/

host0/bus0/target0/lun0:

host0/bus0/target4:
lun0/

host0/bus0/target4/lun0:

host1:

Also, rlogin and remote printing to birdseye have conked out for some
reason.  I can't do a remote backup to the tape drive even if I mknod
/dev/st0.  Is this a coincidence, I'm wondering, or also the work of
devfs?

I see nothing in the list archive about these problems, and so assume
others aren't having them.  What am I doing wrong?
