CentOS 6 entered Maintenance Support 2 (see
https://access.redhat.com/support/policy/updates/errata/ ) on May 10th 2017
and now only receives critical updates. It will go EOL on 30 Nov, 2020 --
in 1 year, 33 weeks, 3 days, and some hours... shortly after that it will
be moved off to archives like C5 and C4 before it.

As much as I *hate* systemd, you should be aware that C 6 is EOL next
year, and then there will be *no* updates to it.

       mark "suppose I should start looking at C8"
