Stopping and starting without forking to verify again:
root@j-nfs-blkmapd-crash:~# systemctl stop nfs-blkmap.service
root@j-nfs-blkmapd-crash:~# blkmapd -f
blkmapd: open pipe file /run/rpc_pipefs/nfs/blocklayout failed: No such file or directory

Service runs without crashing.

Jammy verification succeeded.
