The documents as I understand them state that any argument to a script 
is passed via the syntax ::. Putting the options in as you specified 
makes haresources think that this is another script that needs to be 

With that in mind I tried as a separate script `mount -t reiserfs -o 
remount rw,acl,user_xattr' but that didn't work either.

Regarding user_xattr this installs into fstab as part of SLES 9, I 
suppose when using reiserfs.  According to the documentation that I 
found: "This patch uses the REISERFS_UNSUPPORTED_OPT flag to denote 
-o(no)acl, and -o(no)user_xattr as unsupported, but allowable, when 
support isn't built into the kernel." This seems to say that this is a 
patch to allow acls and attributes to be used when not compiled into the 
kernel.  Maybe someone at SuSE could shed some light on it.
