Hellebo Knut sez:
=================
Most well known DAT drives work (HP, Exabyte, etc..). However some of them
might require special device table entries to care for hardware compression
and other vendor specific features (have a look at the file
/sys/data/cam_data.c)

Hellebo Knut's reply:
=====================
Yes, the above solution is possible. There's been a discussion about this
earlier in this list. Have a look in the archives.
David Gempton's response:
=========================
I ran into this problem when I was setting up a system with 3000 user accounts.
None of my users were members of more than 1 group. So what I did was simply
not put them in the group file.
When they log in their group membership is obtained from the /etc/passwd file
not /etc/group. In my case this worked well.

This line does you no good, (well it adds the *users* ppp1,ppp2 etc to the
group ppp, but as you presumably don't have any users with those names, it
has little effect).

So long as all these GIDs are the same, this creates a large group (I think
any of the names could be used to refer to it, but the top one is the one
the system returns).

We actually produce lines like:
staff:*:22001:fred,mary,john,...,staffX
staffX:*:22001:matha,sam,richard,...,staffY
staffY:*:22001:matthew,sarah,jane,...
so that we can follow down from staff to the other lines that also specify
the group, the staffX and staffY at the end of the lines don't actually
have any function. These lines are produced by an inhouse database of
users. We have groups with over 1500 members.

Each line of the group file has a length limit on it, although the man page
is silent on the matter.
