So, although 50-udev.rules seem to indicate that ttyIx will have group=uucp, they still end up with group=root. /dev/ttyIx are also listed in /etc/udev/static_devices.txt, but as far as I can see that is not related to ownership.
If they are in there it means that they are created during boot rather than dynamically by udev. Unfortunately that file only specifies permissions but no ownership. I guess the best you can do is to use boot.local to adjust the ownership. Note that group uucp really only is for uucp. Don't use it for any other purpose.
Thanks Ludwig - more questions :-) why was the group changed from uucp to root in 10.0? I've just checked a 9.0 system - here the ttyIx devices are in group uucp. The ttyIx devices really just emulate modem-devices, a bit like ttyS* - which by the way are still in group uucp. I'm not really too bothered which user/group I need to use for ttyIx, as long as it isn't root. What would you suggest I use? I'm not sure, but to me it looks like something got unintentionally changed with ttyIx? /Per Jessen, Zürich
