Hi Jeff,
Question for you, what happens when someone wipes out a 
filesystem in a non-global zone?


That depends on how the file system was configured into the zone, and also on 
what you mean by "wipe out."


If the file system was mounted into a zone with "add fs" in zonecfg, then
the most damage that the root user of the zone can do is delete the files. 
Direct device access is not possible, so it's not possible to damage the file 
system structure itself (unless there's a bug, of course, but I don't know of 
one).


If the global zone admin gave a zone block or raw device access to a disk 
slice, then the zone's root user can destroy a file system that has been 
created on the slice. "What happens" is "the same thing that happens in a 
non-zoned system."


Does that help?

Hi Jeff,
you said

The CIS zone will have student users with root (or most likely sudo) 
access.  That kind of access is needed for the classwork.
We felt that a zone would be a much better solution to this
than just letting them have root access on a stand-alone machine
in our computer center.

Considering that a typical networking class has a maximum 
of 35 students, I think I will just byte the bullet and make them home
directories.  If I am careful about UID GID I should still be able to 
still use LDAP (I think).

Question for you, what happens when someone wipes out a 
filesystem in a non-global zone?

Thanks again,
Phil

Why do you want to do that?  Each zone has its own namespace.  Unless you are 
using a network-based directory service, this means that each zone has 
separate user accounts.  If the zones are sharing one /export/home, you must 
ensure that the user names and userID's are unique among the zones.


If you are trying to get the zones to share the global zone's /export/home 
partition, it would be safer to create multiple directories in /export/home, 
one for each zone, e.g. /export/home/zone1, and then LOFS-mount that directory 
into the appropriate zone.

What is the best way to do this?

Seems like I have 3 choices:
1 add inherit-pkg-dir, set dir=/export/home, end
2 add fs,set dir=/export/home, set special=/export/home,set type=lofs,add 
options [rw,nodevices], end
OR 
3 nfs mount /export/home from the global zone, to the NGS (CIS2) later on.


Is there any prefered method to do this?

Also, the passwords for the accounts, is there a recomended way to deal with 
that on the NGZ?



No. 3 is definitely out.  You can't have an NGZ nfs-mount something from 
the GZ on the same box.  Bug.  No. 1 is out if you want users in your 
NGZ to be able to write into those home dirs. inherit-pkg-dir is read-only.

Hi Edna, Jeff, Jerry,

Thank you for all the good input.  I've decided to go ahead with a mounpoint at 
/zones

Since this is a small test box (sbv120) and I have one slice to play with it 
seemd to be a good spot.

Last question for you all, (maybe it should get its own thread), I would like
