Stephen,

Thanks for the note.

This was the point I was missing.  Thanks.  By the way, would it not
be useful to have some command line option that allowed iscsifs to go
into the background?

When I run iscsifs on the amd64/5.0.2 machine, I do in fact see stuff
under /mnt on another terminal.  Thus, something changed between 5.0
and 5.0.2 to make this work and 5.2 may not be required.

     # mount
     /dev/puffs on /mnt type puffs|refuse:mnt (nosuid, nodev)
     [ ... other stuff deleted ... ]

     # ls -lR /mnt
     total 64
     drwxr-xr-x  2 root  wheel  512 Aug  2 09:06 127.0.0.1

     /mnt/127.0.0.1:
     total 64
     drwxr-xr-x  2 root  wheel  512 Aug  2 09:06 target0

     /mnt/127.0.0.1/target0:
     total 448
     lrw-r--r--  1 root  wheel          9 Aug  2 09:06 hostname -> 127.0.0.1
     lrw-r--r--  1 root  wheel          9 Aug  2 09:06 ip -> 127.0.0.1
     lrw-r--r--  1 root  wheel         16 Aug  2 09:06 product -> NetBSD iSCSI  
  
     -rw-r--r--  1 root  wheel  104857600 Aug  2 09:06 storage
     lrw-r--r--  1 root  wheel         43 Aug  2 09:06 targetname ->

Interestingly, if I use "-h localhost" in the iscsifs command it
fails, although other hostnames work fine and localhost is resolved by
the nameserver.

Now, I'm guessing that the current way to mount iscsifs as something
useful is to write up a script to run during the boot process that
will:

- run iscsifs in the background
- run vnconfig on the exposed storage
- mount /dev/vnd?a somewhere

and do the reverse on shutdown.

Are there any such scripts out there that are trying to do this using
the facilities of rc.subr so that they can be used within /etc/rc.d?

Thanks again for your help.  At least now I understand what is
supposed to happen.

Cheers,
Brook
