Good to hear that. I've started to find any difference in +deb9u1 and
+deb9u2 behavior and haven't find any yet :-)

Heh, it's because it's easier for me to ensure the new Erlang version
is in use after the upgrade. In theory there's a possibility of
upgrading Erlang code on-the-fly without restarting the virtual
machine, but I'm not sure it's worth to try to do it for Debian
packages. Also, the Erlang VM is being updated as well in usual
package update scenario.

Anyway, sorry for inconvenience. If I'll find a better way of
upgrading Erlang packages, I'll implement it.

Cheers!
