# Overview #
The fqdn_rand behavior has changed from version 0.24.8 to 2.6 related to #2601
The new function is appending a stray colon onto the end of the fully qualified
domain name string where as the previous version did not, resulting in a
different MD5 seed value.
Old Code: MD5.new(lookupvar('fqdn'))
New Code: MD5.new([lookupvar('fqdn'),args].join(':'))
In the new code, there will always be a trailing colon since args will be nil
or an empty array.
# Expected Behavior #
fqdn_rand should return consistent results across versions
# Actual Behavior #
fqdn_rand behavior is inconsistent across Puppet versions.
# Detail #
I'm not so sure anything should change in the code. There are users likely
relying on fqdn_rand today and I'd hate to see all of their cron resources
change suddenly if they upgrade to a new version.
# Work Around #
For clusters of Puppet Masters where both 0.24.8 and 2.6.4 are executing,
fqdn_rand may be copied to fqdn_random or some other differnt name. This
function may then be deployed as a plugin on both 0.24.8 and 2.6 puppet masters.
Suggest closing this ticket and leaving it in the system for documentation.
