utils
This module contains a number of utility functions used at PSI. It is
the PSI-specific analogue to Puppetlabs' stdlib.
Functions
check_os
Accepts an arbitrary number of arguments, each of which is a string
of the form $osfamily $majorversion as reported by
facter(8). If the facts of the client system do
not match any of the arguments, the function aborts the Puppet
run.
rand_time
This function takes a parameter specifying a time window and returns a specific time within this window based on the MD5 on the hostname. This allows scheduling cron jobs etc uniformly across a fleet of system within a given window, while keeping the time on each system predictable.
The format for the argument specifying the time window is
HH:MM--HH:MM. The window must not include midnight.
The format of the return value is HH:MM.
