Agreed. Good idea!

I'd advice them to use the autogen.sh script, because I guess that rpm
produces this long command line enabling all the features supported (for
instance systemd API requiring systemd-devel and so on). In general,
when configure is run without any additional arguments, it enables all
the features that it is able to with packages currently installed in the
system. I don't think we should require newbies to install sheepdog for

Correct. ./run daemon/libvirtd or ./run tools/virsh. I wouldn't mention
RPM as it would replace libvirtd they have in the system, which is a
stable one with their buggy one. They are new to the project, there
definitely gonna be some bugs in their code.

This should be the default. Correct. I usually join them: make all
syntax-check check.
