hi,

   I seem to be having a problem with /devs and my scsi disks
on my -current system:

FreeBSD FreeBSD.pc.sas.com 3.0-BETA FreeBSD 3.0-BETA #0: Thu Sep 24 18:12:56 EDT 1998     root@FreeBSD.pc.sas.com:/usr/src/sys/compile/FreeBSD  i386


   From dmesg:

DEVFS: ready to run
ccd0-3: Concatenated disk drivers
changing root device to wd0s1a
da0 at ahc0 bus 0 target 1 lun 0

   However, these devices are not showing up in /devs.

FreeBSD# ls -al /devs/d*
crw-r-----  1 root  kmem    4,   0 Sep 24 18:24 /devs/drum
FreeBSD# 

   From my fstab file:

devfs                   /devs           devfs   rw              0       0


   Could someone point out what I am missing?

thanks,
John

ps: I had to create a /dev/xpt0 by hand for camcontrol, it isn't
    in MAKEDEV.

    device xpt0 is not listed in LINT... should it not be there?

    devfs_add_devswf() can return NULL (not documented in the
    man page), and the rc is not checked in the calls to it from
    kern/disk_subr.c ....

    Comments? Critiques? Am I losing my mind? I mean my disks?


    Ok, I give, I just found one of my disks under /dev/sd0 .. I
    must have my kernel config file messed up... any ideas?
