"exactly" resources #143
Description
Some resources, e.g. pkg, perhasps user, group, svc, could have an "exactly" function, which would ensure that exactly the listed resources exist, removing extraneous ones and adding missing.
I've never seen this before, which probably means it's a pointless idea. Certainly the lists could end up very big. It wouldn't be too hard to implement though.
(user/exactly "root" "daemon" "bin" "sys" "adm" "dladm" "my-app")You'd get an error if there was no (user/ensure "my-app" ...), and every user bar the ones listed would be removed.
