[gentoo-dev] devfs - scd0&1 devices

[Collins Richey]

I've got devfs working almost the way I want it.  The stock
/etc/devfsd.conf retains the permissions I've set for sound devices, but
how can I make it hang onto /dev/scd0&1 for my ide-scsi cdroms?  Right now
I have to do MAKEDEV each time I want to use them; they disappear with
each boot.

Use /dev/cdroms/cdrom0 and 1 instead.
If you create new devices of the same type somewhere else in /dev, they will
get backed up and restored as long as devfs is running.

Thanks.  Interestingly enough, devfs generates them on my system as
/dev/cdroms/cdrom4 and cdrom6 !!!

I've just learned from a user on another group that devfs will add the
/dev/srn entries (expected by some applications) if you modprobe sr_mod,
so I've added sr_mod to my /etc/rc.d/config/modules.

both /dev/cdromn and /dev/srn are actually symlinks, ie
/dev/cdrom4 -> /scsi/host0/bus0/target0/lun0/cd
/dev/cdrom6 ->  ...                         /target1/ ...

if only ide-scsi is modprobed, cdrom4 and cdrom6 are generated.  If sr_mod
is also present, cdrom0 and cdrom4 and sr0 and sr1 are generated.
