Isn't the /dev/ppsN device only created when the N_PPS ldisc is set?
In which case there is no point in invoking ppsldisc when the device
is created.

I think the most convenient thing to do to overcome the various
problems, including the problems brought up by Reg, is to set up the
boot scripts to create the /dev/ppsN device nodes which will be used
on the system.  For those running Debian GNU/Linux, this can be done
by modifying the /etc/udev/links.conf file.  If the device nodes are
created statically then the only remaining issue is when to call the
IOCTL to set N_PPS.  The udev rules may also need to be modified so
that the device nodes are not removed when the device driver is
unloaded.
