From ff24f484afbbde86aef3f8850034e3e42977db32 Mon Sep 17 00:00:00 2001 From: Matthias Treydte Date: Tue, 31 May 2022 16:42:33 +0200 Subject: [PATCH] nixos/systemd-boot: fix systemd-boot-builder refusing to update Handling of the string length condition in should_update was broken, as evident with the log message > leaving systemd-boot 246 in place (250.4 is not newer) Discussion with @mweinelt came to the conclusion that Python's "<" operator already does what we need, so the should_update function can be dropped.
