Is there a way to copy a source file to a temporary location? Or to
download a file by comparing it to a different file? The problem I am
trying to solve is updating crontabs when the source file changes.
Our crontab files are checked into version control, synced by "file"
to a temp file, and applied with "crontab". For various reasons, we
can't use the cron type.
define crontab($host = $hostname) {
$path = "/tmp/$name.$host.cron"
remotefile { $path:
source => "operations/cron/$host/$name.cron",
}
exec { "crontab-$name":
command => "crontab -u $name $path",
subscribe => File[$path],
refreshonly => true,
}
}
The problem is it compares the source file to the temp file. If is the
crontab is changed manually, this doesn't notice. In fact, it only
syncs when the temp file is deleted weekly by tmpwatch. It should be
possible to compare the source file with /var/spool/cron/$name. I
would prefer to use the "crontab" command to install it which means
downloading to a temp file. I am guessing that the issue shows up with
other files that need to be installed with a command.
