Issue #11364 has been updated by John Florian.
Here's a concrete example, where I'm attempting to set up an initial password
for VNC sessions:
<pre>
exec { 'set-vncserver-password':
command => "runuser -l $user -c \"umask 0077 && echo $password |
vncpasswd -f > ~/.vnc/passwd\"",
require => Package['tigervnc-server-minimal'],
unless => "runuser -l $user -c \"test -e ~/.vnc/passwd\"",
}
</pre>
Obviously, this example illustrates the necessary kludge of using runuser,
instead of simply using the "user" parameter to make the "~" reference to the
appropriate home directory. Please be aware that I cannot simply replace "~"
with "/home/$user" because our users' home directories don't share a common
parent directory. Instead their path is something more like
"/home/<DIVISION>/$user" and the <DIVISION> is not readily available to puppet
nor should it need to be.

Bug #11364: Documentation not explicit enough regarding UID/GID of exec

When reading the docs for the "exec" resource type, it is not clear what
UID/GID will be used when executing "onlyif" and "unless". In my testing, it
appears that these commands will run unaffected by the "user" and "group"
parameters and if that is indeed the case, I'd argue that to be a bug. If the
commands reference things like $HOME or ~, they are likely referencing the
wrong such ones rather than those specified by the "user" and "group"
parameters. In any case, the docs could be more clear regarding this behavior.
