 Subject: re: How to get access scsi CDROM?

 see cdrom(3) and dossrv(4) for details.

 9660srv can serve several CDROM devices.  you select a particular one
 using a parameter to the mount command; see bind(1).

 [this assumes scsi cdrom at device 4, and /tmp/386allproto]

 % 9660srv
 % bind -a '#R4' /dev		# note the '...' protecting the # in #R
 % ls -l /dev/cd4		# should show something useful
 % disk/kfscmd allow
 % mkdir /n/cd
 % mount /srv/9660 /n/cd /dev/cd4
 # now the contents of /dev/cd4 are visible under /n/cd,
 # in the current name space.
 % /n/cd/386/bin/disk/mkfs -a -s /n/cd /tmp/386allproto |
	disk/mkext -uv -d /n/kfs

 you can also name the #R device directly in the mount command,
 without the bind:
 % mount /srv/9660 /n/cd '#R6/cd6'

 note that if you mount the Plan 9 CDROM this way using the 4 diskette
 system, you can try:

        bind -b /n/cd/386/bin /bin
        bind -b /n/cd/rc/bin /bin

 and make something nearer the full command set available.
 (you might then need to do something similar for /sys and /lib
 for commands that need special data files.)

 old install.ms used:
	% mount -c /srv/il!* /n/kremvax
	% mount /srv/boot /n/boot
	% disk/mkfs -a -s /n/boot /lib/proto/allproto |
		time disk/mkext -u -d /n/kremvax; chmod 770 /n/kremvax/sys/src
