The date/times encoded into the file names below
are those shown for base.txz . The overall artifact
directory date/time is somewhat later. The -good
vs. -bad suffix indicates the boot status.

Side note about /boot/msdos :

The Oct-07 snapshot of main [so: 14] has:

# ls -Tld /boot/msdos /boot/efi
drwxr-xr-x  1 root  wheel  16384 Jan  1 00:00:00 1980 /boot/efi
