[GRASS-user] GRASS and reading mapsets on NTFS

[Patrick Giraudoux]

Dear listers,

I have just migrated from a computer double boot (Windows/Ubuntu Hardy) 
with user data on a FAT32 partition to a new one with a NTFS partition 
instead. All went OK except that I can read mapsets only when grass 
(6.3) is started with sudo. If not, I can access locations in the 
grassdata folder but maptsets are not read. Googling a bit within the 
list I understand that grass can read only with owner rights (and not 
only read/write permission) and this explains the difference. I agree 
with comments that this it looks like a bit over the  top regarding 
security (I may be wrong...).

Of course a solution would be to alvays work as "super user" (sudo) with 
grass on the NTFS partition, but this is obviously not safe and not in 
the spirit of Linux... On the other hand, I cannot move the data on the 
ext3 partition since it was not designated for that (space is limited) 
and more importantly I suppose this would make problem to read from 
Windows (e.g. from QGIS under windows - teaching purpose)....

I would really like to use the NTFS partition to get the data shared by 
the two systems.

As anyone an idea about a workaround ?

Patrick
