» Loop mount iso files without being root

There is a rather convenient way to mount ISO files (CD/DVD images) onto a directory on Linux, which goes as follows:
mount -o loop,ro /path/to/image.iso /path/to/mountpoint
(where the mountpoint is a directory).

This method works very well, but has one essential drawback: you must be root in order to do that. So how do I get to do so as a regular user ?

A barely known alternative lies in fuseiso, which uses the FUSE filesystem in user-space layer to accomplish that.

In order to use it, you must install the package fuseiso, which is available with the openSUSE distribution, and from the release repository (e.g. for 11.4) as well as from the filesystems repository and OBS project:
zypper install fuseiso

Once that has been done (as root ;)), you can simply mount ISO files like this, without being root:
fuseiso /path/to/image.iso /path/to/mountpoint

Note that as an additional benefit, fuseiso also supports images in NRG, BIN, MDF and IMG (dd) format, as well as zisofs.

In order to unmount, simply use fusermount -u, e.g. like this:
fusermount -u /path/to/mountpoint
