Not sure, but F16 also has systemd 37, which is certainly recent enough. I imagine wheezy will soon inherit 37 it from sid, so no problem there.

If pcscd is set to start on-demand, first call to SCardEstablishContext() could possibly delay client application for quite some time. Now, if pcscd was started when the hardware is connected, we would be able to be get rid of the initial delay, and also possibly completely avoid starting pcscd when there's no supported hardware. (Not sure if that would work in practice, with e.g. serial readers.) >>> I also added the --auto-exit option to pcscd so that the daemon will >>> exit when no more needed. >>> The daemon is started when needed using the systemd socket activation >>> method and will exit automatically when not needed. >> >> Not sure ...

Automatically stopping pcscd after some time also means that client apps will experience the same initial SCardEstablishContext() delay all over every time pcscd has automatically exited. -- Kalev _______________________________________________ Muscle mailing list [email protected] http://lists.drizzle.com/mailman/listinfo/muscle
