Describe the solution you like

A clear and concise description of what you want to happen.
(e.g. I would like an input field in the /ui/firewall/alias which would add .... to ....)

Back now to test this and it seems that cd2c3b0 should do the trick.

To apply for testing:

# opnsense-patch cd2c3b0

Rebooted the system and checked /etc/ttys and "on" was still there!

Thanks, we will consider a backport to 21.1.4 or 21.1.5, not sure which yet. Back in the office on Friday. ;)
