Re: [MirageOS-devel] removal of deprecated config in mirage 3.0 (mirage configure --unix/--xen, add_to_opam_packages, add_to_libraries)

[Drup <drupyog+caml@xxxxxxxx>]

To be a bit clearer:

- `--unix` and `--xen` are independent on `get_mode`, so the decision to 
keep them or not is independent.
- I introduced them only in order to keep backward compat. I realized 
when introducing the alias stuff that it was actually fine, hence no 
need to deprecate them (I simply removed usage in skeleton/www, to 
encourage -t).
They were deprecated in an earlier (alpha) version of functoria, which 
is probably why you were a bit confused.
I agree with Daniel that it would be be best to remove them, as it's 
never good to have many ways to do something. I'll let you decide if 
it's worth the breakage.
