Wondering what the various advantages/disadvantages of having a shorter Long Term Support (LTS) support period were over longer ones.
I notice Ubuntu provides 5 years of support, Red Hat Enterprise Linux (RHEL) has 7 years, and Novell has a 10 year support cycle.
Are these numbers essentially meaningless beyond 3-4 years (i.e., servers are replaced/upgraded by then)? Or is there a benefit to the different support durations?
