Puppet

When using a special parameter (e.g @reboot …) to create a cron entry the entry is added to with a title comment “# Puppet Name: …” just like a regular entry. However when the entry is modified the comment is dropped. Because there is no longer a comment title if the entry is modified again, instead of replacing the old line, it will add a new line complete with comment. The old line is now left orphaned.

Example:

cron{ "test":
    command => "/bin/echo One > /tmp/puppet.txt",
    special => "reboot",
}

gives:

# Puppet Name: test
@reboot /bin/echo One > /tmp/puppet.txt

changing to:

cron{ "test":
    command => "/bin/echo Two > /tmp/puppet.txt",
    special => "reboot",
}

gives:

@reboot /bin/echo Two > /tmp/puppet.txt

changing again to:

cron{ "test":
    command => "/bin/echo Three > /tmp/puppet.txt",
    special => "reboot",
}

gives:

@reboot /bin/echo Two > /tmp/puppet.txt
# Puppet Name: test
@reboot /bin/echo Three > /tmp/puppet.txt
