Rare project developers

[Alexander Gall <>]

Hi

I experimented a bit and I think I have a method that performs the
"release-manager --switch-to-generation" from the ExecStopPost script
when freerouter terminates with RC 3 (after "reload warm"). I didn't
see the need to use neither daemonRun nor ptyRun, though (apart from a
glitch in release-manager that causes an issue when there is no
terminal connected to stdin, which I'll fix). The tna-upgrade alias
would then only do the installation but not the switch to the new
version.

However, the "--install-git" variant is only one of the available
upgrade options. There is also "--install-release" and
"--update-rlease". And the user might also want to switch to an
arbitrary installed version or do a rollback to the previous version.

So, we should either create an alias that allows the user to pass
arbitrary arguments to release-manager or expect the user to run the
command from a terminal for those cases.
