I have trouble believing that that works completely, and if it does, I
would be amazed to find that it avoids running the package tool separately
for each package.
Ways I imagine it might fail include:
- Puppet attempts to manage a single package whose name is a
concatenation of the names in $packages ("firstsecondthird...")
- Puppet manages only the first package listed in $packages, ignoring
the others
- Puppet does not correctly detect when the packages are already
installed, and therefore attempts to install them on every run
If it does none of those things then I have great difficulty believing that
it does not create a separate Package resource for each element of
$packages, and therefore indeed run the package manager once for each.
And if it in fact behaves exactly as promised, then that constitutes
undocumented behavior, and it is therefore unsafe to rely upon.
So don't do that.
