This is finally fixed: https://git.savannah.gnu.org/cgit/guix.git/commit/?id=d904abe0768293b2322dbf355b6e41d94e769d78 (Mathieu, Florian: let me know if anything looks fishy.) The commit log says it all. With this patch, a new FIFO is opened after each keymap-change request so kmscon no longer polls on a stale file descriptor. I’ve verified that keymap choices in the installer are honored, that you can change anytime via the F1 menu, and that there’s no file descriptor leak in the kmscon process. Now people will be less likely to hear the fan of their laptop right from the start of the installation process. :-) Ludo’.
