The next problem is that one can't load any modules; is this by design
or I have again made some mistake? Only the two modules prior to
pivoting are seen - solaris and zfs; after that one gets, e.g.:

➜ ~ ls -l /stand/amd64/9.99.47/modules/dtrace/dtrace.kmod
-r--r--r-- 1 root wheel 320120 Feb 20 10:19
/stand/amd64/9.99.47/modules/dtrace/dtrace.kmod
➜ ~ modload dtrace
modload: dtrace: No such file or directory
➜ ~ uname -a
NetBSD nzfs 9.99.47 NetBSD 9.99.47 (GENERIC) #10: Sat Feb 22 14:18:50
GMT 2020 sysbuild@ymir:/home/sysbuild/amd64/obj/home/sysbuild/src/sys/arch/amd64/c
ompile/GENERIC amd64
