is there a way for users to use mount.
for instance to mount an iso image in their home directory to a directory in
their home one.
i'm using slackware and it says only root can do that

If you designate the mount as "user" or "users" in your /etc/fstab,
then an unpriviledged user can issue the mount for the mountpoint. See
mount(8) and fstab(5). The mount(8) manpage contains the following
example...

Normally, only the superuser can mount file systems.
However,
when fstab contains the user option on a line, anybody can
mount the
corresponding system.

Thus, given a line
/dev/cdrom /cd iso9660 ro,user,noauto,unhide
any user can mount the iso9660 file system found on his CDROM
using the
command
mount /dev/cdrom
or
mount /cd

ok let's assume i don't want to make an entry for each iso file that users
download and want to mount -oloop
more over i don't want to be aware of the tonnes of iso files they use.

It may be possible to hard link the iso file to a known name first.
(for example cd.iso)

It`s also possible that /etc/auto.misc can be used, but I will not even try :-)

user1 -fstype=iso9660,ro,nosuid,loop /home/&/cd.iso
user2 -fstype=iso9660,ro,nosuid,loop /home/&/cd.iso
(or maybe :/home/&/image...)

And enable auto.misc in /etc/auto.master, and start autofs

If it works as I hope, then user1 just have to do
cd /misc/user1 and /home/user1/cd.iso will be mounted there if it exist.
(and unmounted short after it's unused )

A symlink /home/user1/something kan be make to /misc/user1

I have never tested auto.misc, so it's just another suggestion if you really
must have this function.

One can also make a /usr/local/bin script that do the job, and add it to
/etc/sudoers for a group of users.
Example sudo /usr/local/bin/isomount name.iso

/bb

'man mount' and 'man sudoers' could be interesting to peruse.

IOW, a specific command to mount X_resource to Y_mountpoint could be
included in /etc/sudoers so that a user could mount something
somewhere specifically. The user's password may or may not be
required, as decided by sysadmin (you?), meaning a user would never
need to know the root password to do such things. Kinda neat when you
have multiple users you can't trust that far. ;)

Probably better ways that this though.
