Description Ulrich Müller gentoo-dev 2005-10-06 01:03:19 UTC
This is concerning /dev/ttyS* (and probably /dev/ttyUSB*, too):

udev-070 sets (in /etc/udev/rules.d/50-udev.rules) the group ownership for
serial ports to "tty".

/sbin/MAKEDEV (from baselayout-1.12.0_pre8-r2) sets the group ownership for
these ports to "dialout".

For consistency, static /dev should be changed to "tty", or udev should be
changed to "dialout". (Or both should be changed to "uucp".)

See also bug #108069 and bug #108088.
Comment 1 SpanKY gentoo-dev 2005-10-06 19:24:07 UTC
switching both udev and MAKEDEV to uucp sounds good to me ... both debian and
fedora are doing that now ...

how about it Greg ?
Comment 2 Greg Kroah-Hartman (RETIRED) gentoo-dev 2005-10-06 19:29:28 UTC
What, and break everyone's systems that rely on the tty group for their users for
these devices?  That's really not a good idea...
Comment 3 SpanKY gentoo-dev 2005-10-06 19:46:42 UTC
*shrug* damned if you do and damned if you dont

Hm, udev rules are config-protected. So nothing should break for existing systems.

dah-dit-dah

Any news on this issue?
Comment 6 Greg Kroah-Hartman (RETIRED) gentoo-dev 2005-12-11 12:14:13 UTC
Well, someone needs to just make a decision about what the group should be
for tty devices, and I'll modify udev to go along with it.

My opinion is to stick with what we have now.
Comment 7 SpanKY gentoo-dev 2005-12-11 17:31:50 UTC
as i said in comment #1, i think changing to uucp is the way to go
Comment 8 Bob 2006-02-07 23:15:13 UTC
is it possible that this "intermittent" device problem is responsible for making serial mice jumpy and totally unusable in X11 with the current 2.6.15-gentoo-r1 kernel?  is so, I think that the severity of the problem should be upgraded to "blocker."  its a definite deal breaker.
Comment 9 Greg Kroah-Hartman (RETIRED) gentoo-dev 2006-02-09 13:33:06 UTC
No, this should have nothing to do with intermittant use with X, sorry.
Comment 10 SpanKY gentoo-dev 2006-12-30 01:55:05 UTC
baselayout-1.13 has transitioned to a sep makedev package which uses 'uucp'
Comment 11 Roy Marples (RETIRED) gentoo-dev 2007-01-10 12:14:38 UTC
baselayout-1.13.0_alpha11 is in the tree which now deps on sys-apps/makedev.
Comment 12 Matthias Schwarzott gentoo-dev 2007-01-27 12:35:47 UTC
Fixed in udev-104-r4.
