Hello,
First I want to point that I am completely new in puppet, and I am
playing a little bit around with it. I am still learning the language.
In our site, we have AIX and Linux systems. I find that puppet has
some lacks on AIX, and probably we will code some providers and
recipes.
Is there anybody working extending puppet for AIX?
How is the best way to share our improvements and colaborate?
AIX have two main advantages that might make providers and new recipes
easy to implement:
* Almost everything can be done with commands
* it is homogenous: most commands have very similar syntax and
output, it does not change between versions...
An example of this can be this snippet that I paste here.
# Define to implement AIX nfs mountpoints. It is based on commands
lsnfsmnt and mknfsmnt.
# It will:
# * Check if the mountpoint is defined.
# * If is defined, check the options.
# * If options change, remove it and create it (it will umount if
needed)
#
# ensure:
# * present: Create/Change it in configuration and running mounts
# * absent: Create/Change it in configuration and running mounts
# * configured: Change only configuration
# * mounted: Do not change configuration, just mount it.
# * umounted: Do not change configuration, just umount it.
# * unconfigured: Do not umount it, remove configuration
