I'm looking for ways to better manage our servers, and right now I'm playing with puppet.
I immediately ran in to a problem: it picked the wrong domain name. Internally at Sun we use NIS (yes, I know it is insecure and sucks in almost all aspects, but I'm not in position to change it - and believe me I have tried) and our NIS domain name doesn't match the DNS domain name.
This is something puppet (facter to be exact) doesn't figure out, at least not on Solaris.
Instead of picking the correct fqdn for a host, e.g. puppetd.sfbay.sun.com,
it picks puppetd.mpklab.sfbay.sun.com,
since that is what the domainname command returns.
They tried to
fix
this, but unfortunately it doesn't work for Solaris,
as it relies on the dnsdomainname which we don't have.
I've worked around it by creating my own /usr/bin/dnsdomainname which gets called before
domainname.
#!/bin/sh
DOMAIN="`/usr/bin/domainname 2> /dev/null`"
if [ ! -z "$DOMAIN" ]; then
echo $DOMAIN | sed 's/^[^.]*.//'
fi
So now I can continue to test my puppet configurations...
s/domainname/\/usr\/bin\/domainname/
Just to be pedantic.

hello,
I've been using puppet for a few months now. To be honest i've found ruby (which puppet relies on) to be exceedingly unstable segfaulting quite often.
Also we have solaris sparc somewhat less stable with puppet than solaris x86.
