- "ok, this is most probably 'sftp', as it's a SFTP-based access"
I would never have guessed that the Apache configuration was in the sftp vserver! I suppose we could have gotten there eventually by brute force search if you were unavailable, but if you can bring yourself to write a sentence about how each of the vservers is actually used, that would go a long way towards demystifying the savannah setup, at least for me. Right now https://savannah.gnu.org/maintenance/VirtualPrivateServer merely talks about different vserver packages, apparently ancient history. vservers.txt goes into lots of nice details about the install, but again, I don't see anything about what jobs each actually performs. Anyway, thanks for all the details. karl
