A quick update on GNU rush (a restricted shell allowing scp / sftp / git / cvs / svn / rsync that should eventually replace rssh which has been removed from Debian repos)
Rush’ developer has produced 4 new versions (current is version 2.2 with a newer much better syntax), but Debian is still stuck at v1.8 and the package maintainer seems to be “missing in action” since 2017 …
If it is going to be part of HestiaCP I guess we’d have to build from source (btw there a few Debian patches for rush, the maintainer seemed very knowledgeable).
