autofs trick

hampel · 07-10-2003, 12:41 PM

Hello!

First please take a look at my auto.master and auto.cdrom

auto.master
===========
/mnt/cdrom /etc/auto.cdrom --timeout=60

auto.cdrom
===========
cd -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom

To view the files on a cdrom, i have to enter 'ls /mnt/cdrom/cd'.
Now i need a trick!
What must i write in the config files that it works with 'ls /mnt/cdrom/', too?

regards,
hampel

I would set it up like so:

auto.maser:

Code:

/mnt /etc/auto.misc --timeout=60
.
.
.
etc.

auto.misc:

Code:

cdrom -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom
floppy -fstype=ext2,rw :/dev/floppy
.
.
.
etc.

Hello!

Yes but if i take your example code, i cannot see all my subdirectories in /mnt; eg. /mnt/win /mnt/zip /mnt/other are invisible if autofs is started!
So i would have to make entries for all subdirectories of /mnt in auto.misc!

Do you understand my problem?

Are you automounting all those other subdirs? If not, why not, and if so, why not put them all in the same config file?
As far as I know, you have to have a subdirectory under the mount point referenced in auto.master. Or, I suppose, you could change your auto.cdrom to be an executable program that mounts the drive on /mnt/cdrom, but that's not trivial. . .

Hello,

thanks for your help!
I have found the answer (i should first take a look at the man pages next time) in man 5 autofs:

UNSUPPORTED
The automounter does not support direct maps or mount trees (more than
one filesystem to be mounted under a specific automount point), and
handles SunOS‐style replicated filesystems only to the extent that
mount(8) does.
