Running -CURRENT on my X250 with only the unveil diff, the kernel
paniced while `make build' was installing the newly built binaries.
Next boot would show something like
init: cannot execute /bin/sh for /etc/rc: exec format error
so I ran fsck from bsd.rd and upgraded to the latest snap.
Transcribed panic as well as the output from `mount' below:
