18 # All steps should be idempotent. This means that you should be able
19 # to run them multiple times without depending on anything previously
20 # being run. The idea is that when the configuration changes, "service
21 # plc restart" is called, all dependencies are fixed up, and
22 # everything just works.
25 # we want the resulting myplc to be able to easily skip
26 # some steps. e.g. the packages step takes ages if you install
27 # all rpms under the repository.
28 # We skip steps whose name contains a dot (.) or a tilde (~)
29 # this way the operations would just rename a step name e.g.
31 # mv packages packages.hide
33 # The drawback is, this stuff does not survive an rpm update
34 # but that's maybe a good thing, that all is done at first start
