This is not a huge thing, just a tiny annoyance that should be pretty easy to fix. Basically, after running the diet-config with Samba added, the smb.conf has a couple of conflicting and unnecessary lines. For example, it has “guest ok = no” and “public = yes”, but public is a synonym to guest ok according to https://www.samba.org/samba/docs/man/manpages/smb.conf.5.html. And since they have different values here, it’s a bit ambiguous which one takes precedence. Likewise, it has both writeable = yes and read_only = no, and read_only is an inverse synonym for writeable.
But yeah, that’s all.
