Jira (PUP-2289) Puppet will purge the /etc/hosts if it have some invalid lines

Title: Message Title

Daniel Friesen commented on an issue   Re: Puppet will purge the /etc/hosts if it have some invalid lines Yes, I ran into this issue myself, and I did it without even editing /etc/hosts. ie: Through one mistakes and 2 bugs in puppet I manage to erase the contents of my /etc/hosts puppet using puppet's host type. I needed to ensure that my ec2 instances had an /etc/hosts entry that ensured that the instance's private ip was associated with the hostname in /etc/hostname. Since factor couldn't be relied on and I was using puppet apply I used this puppet code: $fqdn = generate("/bin/hostname") host { "${fqdn}": ensure => present, ip => $ec2_local_ipv4, host_aliases => [$hostname] } Unfortunately due to the fact that the output of /bin/hostname ends with a newline it resulted in puppet adding this to /etc/hosts on the first puppet run (since host didn't bother sanitizing the hostname): ###.###.###.### foo.example.net foo Then on the second puppet run because puppet couldn't read the corrupt syntax it inserted into it in the first place, it went and purged the entire hosts file when trying to ensure that the corrupt entry was in the file.
