[*] This upgrade switches from split-usr to merged-usr layout since
    the corresponding profile is not available anymore.
    Please follow the migration guide.

[#] The developer profiles are gone. Please migrate eventual settings
    to your make.conf.

[&] You will have to do the symlink migration from 17.0 to 17.1 first.

[%] There are no standalone selinux profiles anymore, only hardened/selinux.
