Digging around, I am pretty sure I picked up the INSTALL_MASK tip from something we put out. Only current info I can find so far is on the Wiki: https://wiki.gentoo.org/wiki/Gentoo_Without_systemd#systemd_unit_files History on that page goes back to 2014, but the first mention of INSTALL_MASK looks to have been added by the edit on 22 Sep 2018 @ 19:05: https://wiki.gentoo.org/index.php?title=Gentoo_Without_systemd&oldid=735246 However, I know I've had the INSTALL_MASK lines on several of my machines for a few years before that. In any case, looking into my mail archives, it appears this bike shed has been painted over a few times before: 2012: "Global Systemd USE Flag" https://archives.gentoo.org/gentoo-dev/message/5ca98a9af71db715fa68632ec1335755 2014: "Possibility of overriding user defined INSTALL_MASK from an ebuild?" https://archives.gentoo.org/gentoo-dev/message/c20d9ada8e05dc1707f021ff01d28802 Seems like the sane option is to just drop the INSTALL_MASK and deal with a gaggle of systemd unit files eating up some inode space.
