[Puppet Users] exec's onlyif parameter fails for a bash one-liner

I would like to 'exec' an installation script 'onlyif' an installation
directory is empty. I tried using following bash one-liner however it
didn't work:
<code>
exec{$one_install_script:
require => File[$one_install_script],
onlyif => "[ \"$(/bin/ls -A $one_location)\" ] && exit 1 || exit
0"
}

</code>

It failed with following error:

<error>
err: Failed to apply catalog: Parameter onlyif failed: '[ "$(/bin/ls -
A /srv/cloud/one)" ] && exit 1 || exit 0' is not qualified and no
path was specified. Please qualify the command or specify a path.
</error>

A bash script with above one-liner worked fine though.
<code>
exec{$one_install_script:
require => File[$one_install_script],
onlyif => "/tmp/is-dir-empty.sh $one_location"
</code>

The bash script approach works fine for me. However I am not sure what
is wrong with the one-liner command. Is $(cmd) command substitution or
built-in function 'exit' a problem? Any pointers will be really
helpful.

Hi,

you need to add provider => shell to your exec to get the subshell working

Puppet wont let you run commands that dont have fully qualified paths,
try adding this and it should work...

path => "/bin"

Almost worked, it didn't fail while applying the catalog however it
failed with following error.
