/ might not be the 'optimal' place for a
vserver, which should if possible reside on
a separate partition, but it should be possible
with recent tools (which allow to configure the
path) or symlinks ...

given that, two vserver lie on the same partition
and they have common rpms, then you can 'unify'
those vservers (or to be more precise the static
part of specific or all rpms), creating immutable
but removeable hardlinks (that is what unification
does) ...

that is the idea behind the ILI (Immutable Link
Invert), to allow removal but prohibit modification
so, it _is_ possible to update or just remove a
package for a unified vserver, but you cannot modify
the unified files, though you can remove and recreate
them with different 'not unified' contents.
