Hi, Andrew Tropin <andrew@trop.in> skribis: > From e96d3f6d82b134829fcb31777e81928c73847dcc Mon Sep 17 00:00:00 2001 > From: Andrew Tropin <andrew@trop.in> > Date: Sun, 6 Feb 2022 08:13:49 +0300 > Subject: [PATCH v3] gnu: linux-pam: Change path to unix_chkpwd helper. > > * gnu/packages/patches/change-path-to-unix_chkpwd.patch: New file. > * gnu/packages/linux.scm (linux-pam): Add patch. > * gnu/system/pam.scm (pam-root-service-type): Add unix_chkpwd to setuid. LGTM, minor the patch file name as reported by ‘guix lint’ and missing ‘gnu/local.mk’. However, it looks like my brain wasn’t fully operational when I previously replied, because: --8<---------------cut here---------------start------------->8--- $ guix refresh -l linux-pam Building the following 2418 packages would ensure 6038 dependent packages are rebuilt: […] --8<---------------cut here---------------end--------------->8--- So I went ahead, fixed up the issues above, and pushed to ‘core-updates’. Thanks! Ludo’.

Thank you very much!) When is the next core-update to master merge scheduled?

It’s not scheduled, but it’s likely several months from now… maybe less
if motivated people help drive the effort. :-)
