I'm running a script that needs root privileges. One of its functionality is mounting an attached user HDD by using udisksctl utility. I'm using it like

udisksctl mount -b /dev/sdX --options umask=0000

but when it succeed, it automaticaly mounts it to /media/root/<LABEL>. But since it mounts it in root's directory, a normal user can't use it or unmount it etc.

How can I succeed it? Anything wrong with my umask usage or it is about env variables? (My distro is Ubuntu, I'm using udisksctl for cross-platform issues.)

    It's normal that users can't unmount what other users have mounted, doing otherwise would be a major security problem. What do you want to do? Authorize certain users to access and unmount this specific directory? Are there other mount points under /media/root that you'd want to protect? Why are you using udisksctl rather than calling mount directly?

    sudo -u <yourUser> <mountCommand> might work?

  • My mount script is triggered via a root-privileged program. I want to use udisksctl because there is cross-platform issues for udisks and udisks2. mount command always wants a target directory for mounting but udisksctl automatically mounts it under /media/<username>/<labelname>

  • if there is a user option in /etc/fstab I think a normal user can umount it, otherwise if you can mount in a directory you own then it may simplify things

The idea is you can choose a mountpoint that is accessible. So try:

mount /dev/sdX /target/blablabla -o rw,umask=0000

I've solved the issue. In /media/X/<labelname>, X comes from environment variable LOGNAME
