I don't think that matters at all. pccard support is provided by pccardd while pnp support is provided by controller pnp0 in your config file. I disgree that you'd need more intellegence than what I've proposed. It will easily handle all the dynamic stuff that I can think of, of devices coming and going, etc. I don't see what pnp, pccard, etc have to do with this. They are orthoginal to the problem. My devfsd dynamically deals with devices coming and going. I also disagree that it won't buy you much beyond the shell script. It buys you two things: 1) the ability to chmod /dev/ttyd1 imp and have that change persist w/o any further action. This is certainly POLA for thise case. 2) The ability to insert a modem card and have it have its old permissions and ownerships restored. When the new device arrives in the tree, the daemon will set its meta data properly. However, this does raise an interesting question, which is what is the scope of this daemon?
