Thank you Felix for this idea ! It indeed helped my classes work
without having to set variables in the global scope.
For future reference, here's the idea:
modules/whatever/manifests/init.pp:
case $operatingsystem {
RedHat: {
$wwwuser = "apache"
}
Debian: {
$wwwuser = "www-data"
}
}
import "classes/*.pp"
import "definitions/*.pp"
In modules/whatever/manifests/*/*.pp I have stuff such as:
class wwwuser {
user { "$wwwuser":
ensure => present,
}
}
And finally in my nodes I do:
import "whatever"
include wwwuser
This solution is convenient enough for my needs. But maybe should we
report this as a feature request to puppet developers ?
Does someone know if there is a good reason variables in init.pp
aren't available in autoloaded classes ?
If this is finally the designed behaviour I will put a note somewhere in
the wiki about the workaround.
Marc
