Custom update source - GermanBread/Arnix GitHub Wiki
I want to host my own update server, how do I do that?
Just host your tarball and the associated sha1sum (optional, must be sha1sum)
arnixctl branch you will have the option to switch to a "custom" branch. After you select said option you will be prompted for two URLs (one for the tarball and one for the shasum, the latter being optional) one after the other
