>Description:
I ran sysupgrade on an i386 machine, pointing the cache to:

RELEASEDIR="https://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-11/20251028150036Z/i386/

The install/upgrade went well other than a couple errors in postinstall checks. One phase generated a core file from "sh". Usually these commands succeed.

>How-To-Repeat:
Unknown. This is the only i386 machine I can access, and I am unlikely to roll back to 10.1 now.
>Fix:
Unknown.
