Title:
  lirc init script can create circular symlinks

Status in “lirc” package in Ubuntu:
  New

Bug description:
  Binary package hint: lirc

This is related to bug 697999 and specifically my need to work around that bug.

If, in /etc/lirc/hardware.conf, you set REMOTE_SOCKET to /dev/lircd1 and transmitter_socket to /dev/lircd, then the lirc init script will create a circular symlink loop between /dev/lircd and /dev/lircd1.  The script tests if OLD_SOCKET != REMOTE_SOCKET, but it should also make sure that OLD_SOCKET != TRANSMITTER_SOCKET  Additionally, before removing ${OLD_SOCKET}1 the script should do the same checks, which it currently does none.

A patch for this solution is attached.

My preference would actually to be to use the new socket locations in /var/run/lircd, however, then the the order I create those sockets is irrelevant, as the magical symlinking always symlinks /dev/lircd to the remote and /dev/lircd1 to the transmitter, which is backwards from how I need it to be.  I'm not actually sure what the best fix is here.  Perhaps it could just test if the socket is /var/run/lirc/lircd\d+ and if it is, then just symlink to /dev/$(basename $REMOTE_SOCKET)  If this is an acceptable solution, I can probably write up a patch for this behavior if necessary.  However, there may be other cases the current behavior is designed to correct for.  If bug 697999 gets fixed, then this problem will no longer affect me.
