After upgrade to "systemd" my /dev/ttyS0 shows up as: root:dialout

When I change as root manually to: chown uucp:dialout /dev/ttyS0
chmod 666 /dev/ttyS0
after restart it goes back to previous setting: root:dialout 600
How to change it?
My VituralBox complain and will not start with owner: root:dialout
/dev/ttyS0
It's a udev rule. Mine looks like this, tweak yours
$ grep -r uucp /lib/udev/rules.d/
/lib/udev/rules.d/50-udev-default.rules:KERNEL=="tty[A-Z]*[0-9]|pppox[0-9]*|ircomm[0-9]*|noz[0-9]*|rfcomm[0-9]*",
GROUP="uucp"
You'd put your file in /etc/udev/rules.d/, not in /lib/ as above,
that's
the as-shipped location for defaults

Thanks for the hint Alan.
Mine looks like this:
grep -r dialout /lib/udev/rules.d/
/lib/udev/rules.d/50-udev-default.rules:KERNEL=="tty[A-Z]*[0-9]|pppox[0-9]*|ircomm[0-9]*|noz[0-9]*|rfcomm[0-9]*",
GROUP="dialout"
I think the group "dialout" is OK. What the Virtualbox doesn't like
is the ownership, the first part "root" (root:dialout)
How to influence the first part.
The strange part is that I have upgraded two system and one is
shoring ttyS0 as:
uucp:dialout
and the another one as:
root:dialout.
Hi,
I have the same permissions and VirtualBox (4.3.6) runs just fine.
VirtualBox is picky about the permission of the hard-disk image (VDI
file)
There it likes group vboxusers and group r/w permissions.
