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.
