Hi,
Here is a patch that adds a System-V init script to the
distribution. This script creates/deletes the devices in /dev
and sets the latency through /proc/xenomai/latency.
Please re-run automake before committing (if committing).
Ok, queued for 2.1.1. Thanks.
Is there anything more it should do? For instance, is there a way
to start the timer through one of the /proc/xenomai/*
pseudo-files?
v2.1 starts the timer as part of the nucleus startup procedure, so it should not
be needed to do so on boot. This said, providing a write side to
/proc/xenomai/timer so that we could change the setup on-the-fly looks like a good
idea.

+This directory contains a System-V-style initialization script for Xenomai.

+latency through the /proc/xenomai/latency interface.
+
+To install this script, as root:
+> cp init.d/xenomai /etc/init.d/xenomai
+> chown root:root /etc/init.d/xenomai
+> chmod 0755 /etc/init.d/xenomai
+
+The configuration values are stored in the /etc/default/xenomai file.
+A skeleton is provided in this directory. To install it:
+> cp default/xenomai /etc/default/xenomai
+> chown root:root /etc/default/xenomai
+> chmod 0644 /etc/default/xenomai
+And adapt the values in /etc/default/xenomai.
+
+Then, make the initialization script start in the required runlevels.
+On Debian, you can use update-rc.d(8) or rcconf(8) to do so.
+Or you can also do it manually:
+> for L in 0 1 6; do (cd /etc/rc${L}.d ; ln -s ../init.d/xenomai K20xenomai) ;
done
+> for L in 2 3 4 5; do (cd /etc/rc${L}.d ; ln -s ../init.d/xenomai S20xenomai)
; done
