I just upgraded from openSUSE Tumbleweed 20211008 to 20211031, which included
an upgrade from at 3.2.2-1.2 to 3.2.2-2.1.  Now it's no longer possible for me
to run any commands at all via at or batch.  Trying to do so always results in
an e-mailed error message with the following text:

sh: line 87: cd: /home/psy: Not a directory
Execution directory inaccessible

(Here the line number may vary, and the directory following "cd" is whatever
directory the at/batch command was run from, or my home directory in the case
that the command was run via a cron job.)

I can easily reproduce the problem by running some dummy command via batch. 
For example:

echo sleep 1|batch
