trivial (trivial p `changesFile` f) `changesFile` f'
The parenthesized property here is all marked trivial, so a change to f
won't result in MadeChange, though a change to f' will.
The only way propellor might intercept the output of a program is if you're
using the new Concurrent module. In that case it should buffer program output
and display it all at once. There could potentially be a bug there that
hid program output. I certianly can't reproduce changesFile hiding the output
of a program:
*Propellor.Property.Apt> runPropellor (Host "localhost" [] mempty) $ ensureProperty $ trivial (buildDep ["git-annex"]) `changesFile` "/var/lib/dpkg/status"
