This is currently shared among zones and I suggest to leave it that way
as both zones are probably not fully utilized at the same time - please
keep in mind that the zones share a common kernel. There are resource
capping possibilies available if needed, but at the OpenCSW buildfarm
I never needed them.

SSH Keys are installed on both machnes for root.

Here are IPs:


If you need special CNAMES or a different reverse lookup just let me know.

Compilers have been installed under /opt, OpenCSW packages have been installed
under /opt/csw as usual.

The zpool for the homedirs is still 146 GB for now, I’ll expand it when
the disks arrive. The homedirs should be created at /export/home/<user> once
per user for both zones and are automounted to /home/<user> on each machine
per lofs.

Mosh is installed.

Lots of other OpenCSW packages have been installed in /opt/csw but probable
some more stuff is useful, if there is something missing just let me know.

Setup is described in /etc/SETUP.

Please give it a try and let me know if something needs to be adjusted.

Best regards
