You can use implicit tags, all resource in a class should be tagged by
that class name. So if you have a class called foo, you should be able
to use tag foo to apply them.
If you want to perform this conditionally, you can also use
environment variables to set custom facts and use those facts in your
puppet manifests to include classes resource on the fly.
FACTER_install_foo=true; export FACTER_install_foo
FACTER_install_bar=true; export FACTER_install_bar
Bacause "FACTER_" will be stripped off, in your puppet manifest:
if $install_foo {
include foo
...
}
Thanks,
