Patrick - drifting a bit OT but will answer briefly..

What package will you be using

No final decision yet. Have been a user of Redhat and distributions derived from it since 1998. Was primarily an IBM OS/2 user before that for PCs. For shares, mail, news server, dhcpd, name server etc will probaly be Fedora Server. Been impressed with their migration tool which enables a major OS version upgrade without a re-install from scratch. This workstation started life several years ago as Fedora Release 26 - it is now Fedora 30 having progressed 26 -> 27 -> 28 -> 29 -> 30. Currenly just trying distributions based in Ubuntu such as mate mint etc. The last to change will be firewalls. Suspect it will be pfSense. Used it a few years ago and really loved it. It was only that I was still working then and really didn''t have the time to get to grips with the finer nuances of BSD. Being retired now that isn't so much of a problem. pfSense is fast, reliable and secure - the reporting was brilliant. That provided by ClearOS looks really amateurish in comparison.
