Not too sure I understand what you are saying Aaron.  What is SGID?

That has never been the case before:

[amanda@coyote /]$ ls -l /home/
total 56
drwx------ 26 amanda amanda 4096 Nov 25 07:44 amanda
drwx------ 14    502    502 4096 Nov 12  2002 elmer
drwx------ 41 gene   gene   4096 Nov 25 10:54 gene
drwx------  3    503    503 4096 Nov 21  2002 roadrunner
drwxr-xr-x 18 gene   gene   4096 Aug 14 03:42 shop

drwxr-xr-x  6   1002   1002 4096 Dec 14  2005 spamd

This tree was copied over from the old FC2 /home directory which looks 
like this:

[amanda@coyote GenesAmandaHelper-0.5]$ ls -l /mnt/hdb/home
total 36
drwxr-xr-x 21     33 disk   4096 Nov  8 23:37 amanda

drwx------ 36 gene   gene   4096 Nov  9 16:32 gene
drwx------  2 root   root   4096 Oct 22  2002 lost+found
drwx------  3    503    503 4096 Nov 21  2002 roadrunner
drwxr-xr-x 18 gene   gene   4096 Aug 14 03:42 shop
drwxr-xr-x 19   1000   1000 4096 Aug 13  2004 shop-gene
drwxr-xr-x  6   1002   1002 4096 Dec 14  2005 spamd

Which was done after the user was created.  Now, if I look at the old FC2 
passwd file and grep for amanda, this comes back:

[amanda@coyote /]$ grep amanda /mnt/hdb/disk/etc/passwd
amanda:x:33:6:Amanda user:/home/amanda:/bin/bash

How amanda ever got to be userID 33 I have NDI.

For FC6, I get this:
[amanda@coyote /]$ grep amanda /etc/passwd
amanda:x:501:501::/home/amanda:/bin/bash

But the same on the group file:
FC2:disk:x:6:amanda,root
FC6:disk:x:6:amanda,root

Am I supposed to hand edit the passwd file to change that second number to 
a 6?  That doesn't make sense when I've already used the menu tools to 
supposedly do that.

Here is the contents of that directory:
[amanda@coyote ~]$ ls -l

Now, anecdotal. As root, I chowned that whole subdir of /home/amanda to be 
amanda:disk, then did the make install, then ran a backup which has now 
finished succesfully, everything had enough perms to do its job.  But I 
want this to be automatic like it was on the 21st (that was also built on 
FC6, the earlier ones were on FC2), not something I have to do by hand 
everytime I install a new amanda, which may be several times a week.  I'm 
one of the 'canaries in the coal mine' type testers.
