Hi,
this patch reinstates the vncserver script, which allows the easy
management of tigervnc.
The reason it got removed upstream is that some desktops in combination
with systemd may not work properly.[1] This should not be the case for
OpenBSD.
I've taken the script from 7.0 and works fine for my use case.
Otherwise the port is unchanged.
Thank you op@ for giving me hints!
