Hi Ryan, You can put something like this in /etc/rc.conf to get the device files created automatically: mdconfig_md0=-t vnode -f /mount/disc_images/Image1.iso mdconfig_md1=-t vnode -f /mount/disc_images/Image2.iso mdconfig_md2=-t vnode -f /mount/disc_images/Image3.iso Because these devices (/dev/md0, /dev/md1, /dev/md2) will be created before /etc/fstab is processed, you can then add the following entries in that file: /dev/md0/mount/office_files/images/Image1cd9660ro00 /dev/md1/mount/office_files/images/Image2cd9660ro00 /dev/md2/mount/office_files/images/Image3cd9660ro00 Check out the rc(8) man page (http://bit.ly/fuwn5n) for more information about how the startup scripts work, as well as the one that processes the device creation directives above - /etc/rc.d/mdconfig Finally, you can always add your own custom startup scripts to /usr/local/etc/rc.d if you need to do something that the standard startup scripts can't handle.

Re: Automating mounting of ISO images
We're close on this (thanks for the push).
It wants to load the entire path up in ${DEST} which is not ideal but I can
live with that.
I am also trying to make the directories right before the attempt to mount the
image (a 'duh' moment just now).
So I'd like to have just the filename, not the full path, made as a folder...
In other news: The ISOs are all made by me, so no special chars, just capital
and lowercase letters, sometimes numbers, no spaces and use of underscores and
hyphens.
thanks!

Underscores and hypens are traditionally not a problem. Spaces
can be and need extra attention. But as you're using PROPER
filenames, it should be easy to get the target directory name
from the ISO filename.
The unelegant way is to use basename:
DIRNAME=`basename ${FILE} .iso`
Of course, there's a sh builtin for the same purpose:
DIRNAME=${FILE%.iso}
Adding this to the iteration list, you can easily create
the directories needed prior to the mount attempt.

Just a little note:
Make sure you're mounting the ISOs as -o ro to prevent
write access to them. If users don't have +w access to
the mounted directories, you can leave out this step.
Depending on the permissions used, this might corrupt
(or at least change) the image files which may not be
desired.
If you want to omit one external program call (one per
iteration step), use DIRNAME=${FILE%.iso} instead of the
`basename ${FILE} .iso` - although it's more obvious what
DIRNAME gets designated to. :-)

I did try that once and it didn't strip the directory structure out so when
basename worked I didn't mess with it too much. If we have 100+ ISOs to mount
then I'll worry.

I've just checked - you're right. While `basename` works
as intended, ${%} can be applied to pure filenames only
in this case.

Prefix it with a test:

mount...
so there will be no error if the script is started for the

While I agree with this suggested change from the perspective of only doing
