Hi @Joe and all.
Yup simplify IT… and succes whised! 
I only hope you can give a kind off roadmap upfront?
While as i startet this thread , mean reason is lacking off enough uptodate DOCU and information about changes.
For planning and future, for example hosting company’s nead to know which path the CP they are offering is on.
So most important question and example here i guess: ( to have some “long term” planning for all who use CP Virtualmin / Webmin)
WHICH OS and versions are going to be supported if SIMPLIFied.?
And yes or no still possible to have other REPO / PACKAGES supported by them/ourselves in virtualmin other the the OS …?
I have only 2 small / very small running 1 test only and one for not so important project few sites, with other repos.
What i’m posting is my time investment sharing with forum users here.
Experience with both vps/instances is the reasing of this topic started by me.
Can’t help myself with DOCU because of bad grammar. sometimes however pointing some to links or what is missing.
OK good practical found example of my “complaints” about docu and info’s:
@Joe you started a topic about DEBIAN 8 support here Debian 8 no longer supported in the installer (but updates will continue until June)
BUT you also mentioned CENTOS 6,7,8 in topic normally CENTOS guys if doing quick overview do not read. So clear roadmaps FOR OS and versions needed , then you save time in answering questions.
( and yup roadmaps are only roadmaps , so if time windows are not reached, only post this info there to be transparant and clear in one place for OS / versions , then you save yourself time)
