[syslog-ng] Solaris 10 info

[Dave Johnson]

Roberto--

Good work.

A couple notes--
* If one changes the --cfgfile option, then the svc.method
file should be updated as well (it checks for the config file)...

* We use the convention /etc/syslog-ng/ -> /usr/local/etc here;
If my memory serves correctly, I ran into a small issue between
the builds (maybe it was sunfreeware and a compiled build?). 
In any event, the link was an easy workaround to make sure
syslog-ng starts up (with a config file).

* The other thing is, logrotation may need to be updated (logadm.conf) :
/var/log/syslog -C 8 -P 'Sat May 28 08:10:00 2005' -a 'kill -HUP `cat 
/var/run/syslog.pid`'
/var/adm/messages -C 4 -P 'Sat May 28 08:10:00 2005' -a 'kill -HUP `cat 
/var/run/syslog.pid`'
to
/var/log/syslog -C 8 -P 'Sat May 28 08:10:00 2005' -a '/usr/sbin/svcadm 
refresh syslog-ng`'
/var/adm/messages -C 4 -P 'Sat May 28 08:10:00 2005' -a '/usr/sbin/svcadm 
refresh syslog-ng`'
-----
I'm not sure why Sun doesn't use svcadm to -HUP syslog...

It should be noted, that feature with smf (as Sun touts as automatic 
healing) is that if you 
`pkill -9 syslog-ng` smf will :respawn: a new syslog-ng process.
