Comment(by br...@…):
IIRC, there was some messing about with the usb group in trying to handle
various USB bus devices as non-root users. I can't remember if the issue
was that the usb group was insecure (but needed at the time), or that not
using the usb group was insecure somehow. Alexander may remember.
Otherwise I'll see if I can find anything helpful...
Oh, I see -- it was discussed in BLFS ticket
[http://wiki.linuxfromscratch.org/blfs/ticket/2065#comment:18 2065], which
was (likely) the impetus for this ticket. :-P If the usb group was
created only as a workaround and is no longer needed, then sure, kill it.
:-)
As far as the uucp group, upstream had a conversation recently about the
uucp/dialout groups in rules. Debian (at least) uses the uucp group to
run an actual uucp daemon, and do so securely; users are (AFAICT) not a
member of that group. They use the dialout group to allow users to create
PPP-like connections. I *think* the upstream rules were moving in that
direction, or at least one of the udev maintainers said they liked it. I
don't see the actual udev git tree having changed yet. Maybe it was
forgotten.
I think dialout makes a lot more sense than uucp for those devices anyway
(and would be in favor of s/uucp/dialout/g, plus adding a dialout group),
but I would guess some people may disagree. ;-) Waiting for the next
udev may also be a good idea (that's part of the reason that I haven't
been doing much with our rule differences: they're changing a bunch of
their rules).
