The problem with forking CentOS (or even just seeking to continue building it)
is that you will have all the same issues you have and no-one behind you to
help fix them.
I work (more or less) as a sysadmin - have done for years - and have been
driven to distraction by Red Hat/CentOS at work,
The folks over at Devuan have chosen to name their next code release (based
on upcoming Debian 11) beowulf. I don't think it will impact this list - but
you never know.
