Hi all,
I have an interesting one - Solaris uses a lot of commands to
configure specific items. A simple
example is coreadm. In this example:
# coreadm -p "/var/core/core_%n_%f_%u_%g_%t_%p"
will set the directory and filename to dump core files (with some
expansion).
The question is - how to get this to run only if the config has
changed. I have come up with 2 options, neither of which I'm that
happy with, so I'm open to ideas...
Option 1: Manage the resulting config file.
file { "/etc/coreadm.conf":
owner => root,
group => other,
mode => 644,
source => "puppet:///cores/coreadm.conf"
}
exec { "/usr/bin/coreadm -u":
refreshonly => true,
subscribe => File["/etc/coreadm.conf"]
}
Option 2: Check for individual changes using coreadm:
exec { "/usr/bin/coreadm -p /var/core/core_%n_%f_%u_%g_%t_%p":
onlyif => 'test `coreadm | grep "global core file pattern:" | awk
'{print $5}'` -ne /var/core/core_%n_%f_%u_%g_%t_%p'
}
The problem with option 1 is that Sun don't recommend messing with the
config file directly, and that it
relies on a way to force the kernel to re-read the config from the
file - this may not be possible with other similar commands... It is
the neater option that I have come up with, however...
The problem with option 2 is that it means that I have to run one exec
block for every option I want to control...
Has anyone else attempted to manage these kinds of resources? If so,
what did you do?
thanks,
Greg
