Install FreeBSD 14.0 on Hetzner server

Hetzner no longer offers direct install of FreeBSD, but we can do it ourselves. Here is how :)

Boot the hetzner server in Hetnzer Debain based rescue mode. ssh into it. then:

wget https://mfsbsd.vx.sk/files/iso/14/amd64/mfsbsd-14.0-RELEASE-amd64.iso

qemu-system-x86_64 \

Not everything you want to keep in a VCS is a "project": Sometimes you have one single file which does not belong to any other files, but you still want to have it version-controlled. Assume a TODO file, an Office document or something. How well do various version control systems perform here?

Preface:

$ uname -smr 
Darwin 19.3.0 x86_64

$ sccs -V
sccs schily-SCCS version 5.09 2020/01/31 (x86_64-apple-macosx19.3.0)
