Should this registration api be provided by portage, or by
base/profile.bashrc?
Hmm, will have to be portage, because /etc/portage/bashrc would override
base/profile.bashrc too. base/profile.bashrc just might jump in when not
provided by installed portage yet.

For readability, I'd more like to have 'post' in front of 'install'.

Or eventually something like:

        register_phase_hook \
          --before-src_install my_pre_src_install_1 my_pre_src_install_2 \
          --after-src_install my_post_src_install_1 my_post_src_install_2 \
          --before-<phase-function-name> <multiple hooks> 

Or with phase-names instead of phase-function-names:

        register_phase_hook \
          --before-{setup,nofetch,unpack,prepare,configure,compile,...} <hooks> \
          --after-{...,test,install,preinst,postinst,prerm,postrm} <hooks>

Suggesting "before&after" here as I'm always confused with
pre_pkg_preinst, post_pkg_preinst, pre_pkg_postinst, post_pkg_postinst,
pre_pkg_prerm, post_pkg_prerm, pre_pkg_postrm, post_pkg_prerm.

Anyway: besides implementation, what else does it need to get this done?

Thank you!
