After stumbling upon masked udisks 2.7.1 and having a WTF moment seeing its dependencies, a question: isn't 'WANT_AUTOCONF=latest' (from the eclass) the more correct solution ? (a disclosure: I haven't been keeping up with times, so I've missed those slotting changes in autoconf a year ago, yet the above *should* be still be valid)
commit c2d6258bf26291e43561a3789d7f90a547532117 (HEAD -> master, origin/master, origin/HEAD) Author: Lars Wendler <polynomial-c@gentoo.org> Date: Wed Jul 19 15:22:28 2017 dev-libs/volume_key: No need to depend on specific autoconf slot (bug #625630). Package-Manager: Portage-2.3.6, Repoman-2.3.3
