Hi

I was wondering how effective the vunify is? It looks like I have saved
a very small percentage when I unify a vserver. In my previous post I
thought that it might not have worked as the command ran so quickly.

Looking in more details at the files with lsattr, the unified vserver
has had the flags changed for the files.

For example

----i----------t- testunify/bin/mount
----i----------t- testunify/bin/umount
----i----------t- testunify/bin/ps
----i----------t- testunify/bin/kill
----i----------t- testunify/bin/sed
----i----------t- testunify/bin/date
----i----------t- testunify/bin/echo

Does this look ok?

How do you measure the benefit, would du <vserver> do the job?

All the best

Dan
