in reply to One Perl to Rule Them All
Base this on a change-management system (or version control system), such as CVS, git, Clearcase, or subversion.
Check-in the "canonical" version of perl, then LABEL that version as "canonical".
From that point, each machine checks-out a daily snapshot of the "canonical" branch.
This allows you to change what you think of as "canonical" - after testing the new version, of course. It also lets you revert, in the event that waste matter impacts the rotating ventilator.
