Currently mutt build breaks with

[   22s] checking whether your system's regexp library is completely broken...
no
[   22s] checking where new mail is stored... no
[   22s] configure: error: "Could not determine where new mail is stored."


last change in package filesystem :

 Mon Sep 25 08:45:52 UTC 2023 - Ludwig Nussel <lnussel@suse.com>
 - Add /run/lock (boo#1212926)
 - Remove /var/spool/mail (boo#1179574)
 - Remove obsolete home dir check. The filesystem package is not
   meant to contain home directories of random system users anymore
 - Create ghost symlinks also in pretrans, needed to get /var/run as
   link right away

... and now with /var/spool/mail also /var/mail disapears?
