Subject: cloner: clone serial files
From: Oleg Vasilev oleg.vasilev@virtuozzo.com Wed Nov 30 22:01:08 2022 +0600

Before this, on clone the serial file would remain the same for the cloned
domain. This doesn't make much sense as the output would be an intermix of two
unrelated output sequences.
Here we apply the the same filename changing algorithm, as with disk files.
