man: note that we don't do /dev/input/by-id or /dev/input/by-path

Browse Source 
For logind-setups we need to match the path libinput wants to open with the
Option Device path that the device has so we know when to return the
server-fd. This doesn't work for by-id or by-path because libinput resolves
those (through udev) to the actual eventX node so our paths look different
when they are the same device.

This could be fixed but since this is easy enough to work around with a
InputClass section and rather a niche case, it's not really worth the effort.

This feature is provided by this driver, not by libinput.
.SH BUGS
This driver does not work with \fBOption \*qDevice\*q\fR set to an event
node in \fI/dev/input/by-id\fR and \fI/dev/input/by-path\fR. This can be
usually be worked by using \fBSection \*qInputClass\*q\fR with an
appropriate \fBMatch*\fR statement in the __xconfigfile__(__filemansuffix__).
