Hi Nik,
First, you should only add things to the gac as root, never as a normal
user. We even tought of an additional user-gac, but I think the idea was
dropped.
Second, everything in my gac is owned by user root and group root. And
the permissions are
drwxr-xr-x
for directories /usr/lib/mono, /usr/lib/mono/gac, and for each assembly-
related directory inside /usr/lib/mono/gac and their version-pl.
Taking for example Npgsql.dll instaled in my gac we have a directory
/usr/lib/mono/gac/Npgsql/1.0.5000.0__5d8b90d52f46fda7/
containing
-rwxr-xr-x 1 root root 181760 Mar 21 15:46 Npgsql.dll
-rw-r--r-- 1 root root 106152 Mar 21 15:46 Npgsql.dll.mdb
Assemblies in the GAC are shared content so they must be readable by
everyone. The execute permissions on dlls are just a reminder because
they need to be loaded and executed by mono.
In case you don't know: the execute bits in permissions for directories
are used to mark them as listable (browseable), so if you take them
out the affect user/group won't be able to find/open the files, even if
the files' permissions allow.

Hi,
New to linux (suse 9.2) so please bear with me:
Using mono 1.1.4 all the files in my GAC have owner/group of root. In
my code where i use the Npgsql connector, my code runs fine when
executed under root but under a normal user it bombs out badly:
** (postgres.exe:9267): WARNING **: Could not find assembly Npgsql,
references from /home/nik/postgres.exe (assemblyref_index=1)
Major/Minor: 1,0
Build: 5000,0
Token: 5d8b90d52f46fda7
System error: No such file or directory
** (postgres.exe:9267): WARNING **: Missing method .ctor in assembly
/home/nik/postgres.exe typeref index 2
Unhandled Exception: System.NullReferenceException: Object reference not
set to an instance of an object
Likewise, when using the gacutil to install npgsql from a normal user i
get errors and it mentions permissions.
So what user/group should i be setting the files in the gac to ?? If i
change the group to 'users' with read perms then it complains about
/etc/mono/machine.config
It just doesnt feel right that i need to be opening up all the perms on
things - but maybe this is how linux does things... if so is there any
recommended set of permissions (or have i royally botched something up
with the install ?).
Any help appreciated,
Nik
