#388 udev rule breaks operating systems

[David Chmelik]

When inserting some devices I get critical error "udevd[n]: failed to execute '/usr/bin/sh' '/usr/bin/sh -c '/usr/bin/setfacl -m g:lirc:rw /dev/bus/usb/001/009 2>/dev/null || :'': No such file or directory" so then the devices don't work; their drivers entirely fail. It's not even infrared devices, but all kinds of non-infrared USB devices, etc. The standard shell location is /bin/sh. Use it! Maybe you program on some OS that did the stupid usr-merge, but many aren't doing that, so you should keep the software general for all sorts of GNU/Linux.

How do I reproduce this issue? What distribution do I use and how do install lirc?

I'd like to make sure your fix actually works. This path has been in use way even before usr-merge became a thing, I think.

Install on any GNU/Linux only using standard /bin/sh.  Insert USB
devices such as small wi-fi, bluetooth adapters.

Slackware GNU/Linux, for example.  You can follow your own instructions
or use (as root/sudo) SlackBuild package building script (which follows
your instructions): http://slackbuilds.org/repository/15.0/system/lirc/
.  Afterwards (as root) installpkg /tmp/lirc*z .  I recall this
happening on Slackware 15-stable (which got updates recent days) but I
use Slackware 15+current which has the problem.

Maybe there's a way you can use both?  If they did usr-merge, there's
generally still /bin/sh; /bin or /usr/bin points to the other with
everything (have /bin/sh, /usr/bin/sh, same).  If they didn't usr-merge,
they typically only have /bin/sh.  If I was doing this I'd stick with
the standard /bin/sh.

I did 'ln -s /bin/sh /usr/bin/sh' and then could use USB devices, so I
know keeping standard path works... one shouldn't need to do this
non-standard thing though, and even some/many Slackware users won't know
this.
