That’s expected, yes. What makes you think it’s a problem?
When implementing that, there were several possible choices:
1. Upon rollback to N, remove all generations above N. Rejected
because it gratuitously prevents useful use cases.
2. Upon rollback from P to N, keep all the generations, but use P+1
for the next generation number. Doesn’t work, because rolling back
from P+1 would bring you back to P instead of N.
3. The current behavior.
See <http://lists.gnu.org/archive/html/bug-guix/2013-01/msg00325.html>
for part of the discussion.
Thanks,
