I think I know what the problem is. On Fedora, for the systemd-udevd.service there is this setting. SystemCallFilter=@system-service @module @raw-io then 50-rc_keymap.conf adds: SystemCallFilter=bpf Which is concatenated to the end. On the debian version of systemd, SystemCallFilter is not set. So SystemCallFilter=bpf means that only the bpf syscall is allowed. I'm not sure what the correct solution is. I'll try a few things and if I don't come up with anything, I'll have to revert. Suggestions welcome :) Thanks for debugging and reporting. Sean
