[GRASS-user] Re: user/group permissions for accessing data on mounted drive

Hello,
thanks a lot for the answer (on the weekend) ;-)

OK. I was able to get access using the right uid in fstab.
But let's say that more than  one person uses this computer.
What is the best way to handle this?
I cannot log in, change the uid in fstab and reboot and longin with 
another user account.

Could this not be converted in a configuration parameter?
See the following use case:
A desktop/notebook used by a group of people. Of course, these collegues 
would not work on this machine simultaniously but log in at different 
times with different user names.

Any solutions?

Thanks in advance,
