However, I now noticed a new one: pcscd doesn't seem to be killable

easily (at least not by a TERM signal), so "herd stop pcscd" has

works without problems, though.

no effect. Sending a KILL signal and starting with "herd start pcscd"

The Shepherd's instance hangs at

 strace: Process 11441 attached
 select(7, [6], NULL, NULL, NULL



Kind regards,

I can reproduce this. Interestingly(?) it only affects the pcscd started by Shepherd. Manual $(guix build pcsc-lite)/sbin/pcscd invocations, both with and without --foreground, are eminently killable with TERM alone. with no activity at all when signal 15 is delivered. I don't know any tricks to attach faster to get more leading context.
