Hello,
we are setting up puppet and using multiple environments (development,
staging, qa, production), so far we are trying to keep to the
BestPractices2 from the wiki[1].
Now we need to decide on how to manage different distros. Do you just
create modules for that or extensively use "case" statements with
facts to correctly manage things. I''m really just looking on input
wether you keep a single module that handles say Debian/Etch,
Debian/Lenny, Redhat, Solaris or do you use different modules for
those?
I can''t really decide wether it''ll be less painfull to
case $operatingsystem: {
"debian": {
# do this
}
"solaris": {
# do that
}
default: {
# do even more stuff
}
}
or have modules like:
hosts.debian.pp
hosts.solaris.pp
hosts.default.pp

I''ll try to keep to that, maybe I''ll be able to publicly post our recipe repo too then it''s at least somewhere where common suggestions are leading. Of course that''s not exactly a hard rule one can keep to but I like to keep to a common base as much as possible. thanks martin -- http://www.xing.com/profile/Martin_Marcher You are not free to read this message, by doing so, you have violated my licence and are required to urinate publicly.
