> you need to remember ${process} again That's why sysadmins should be encouraged to never configure systems directly, but use write-apply-observe-refine cycle of Puppet/Chef (or alike) declarative configurations. Sounds like a hassle (and sometimes it is, especially in cases where to-be-configured software has Turing-complete configuration files), but in my own experience actually proved very helpful.
