1. My platform is listed as unsupported. What to do now?
2. Support status for various platforms
3. Getting the uptime on unsupported platforms

1. My platform is unsupported. What to do now?
==============================================

First of all, do not panic. Chances are that uptimed will work on your
platform with little or no modifications.

There are basically three reasons why your platform could be unsupported:

- I have insufficient knowledge to get my code to compile,
- I have insufficient knowledge how to get your platform's uptime,
- I have insufficient knowledge of your platforms startup process and files

2. Support status for various platforms
=======================================

BSD (other than FreeBSD)
------------------------

If someone can tell me the /usr/local/etc/rc.d equivalent for other BSD
systems, these can be officially supported. Thanks!

HP/UX
-----

Uptimed now works and compiles on HP/UX (at least under 10.20) with thanks
to patches from Helge Deller <deller@gmx.de>. Not being an expert on HP/UX
startup files, any help is very welcome here. Currently /sbin/rc is used:
find the following part at the end of /sbin/rc and insert the lines
commented with "insert me!".

---- /sbin/rc ----
# Output message to indicate completion
#
echo
if [ $BOOT = 1 ]; then
	echo "Creating unique uptime daemon bootid..."	# insert me !
	/usr/local/sbin/uptimed -b			# insert me !
	echo "Start uptimed..."				# insert me !
	/usr/local/sbin/uptimed				# insert me !
	echo "The system is ready."
else
---- /sbin/rc ----

3. Getting the uptime on unsupported platforms
----------------------------------------------

I have written a quick and inaccurate hack calculating the uptime from the
current time and the timestamp made at boottime.

This is very portable and thus will also let uptimed run on platforms where
I do not know of how to get the real uptime.

However, this is also very inaccurate, because:

1) the boottime timestamp can be extremely delayed due to fscking etc.
2) when the system time changes (for example timezone changes) the
   boottime timestamp does not, creating even more inaccuracy.

However, this hack should at least _work_.

If you can send me <radek@podgorny.cz> any information on how to get the
uptime on your platform, it will be appreciated very much.
