In updating from circa Oct 18 1.6ZD to yesterday's 1.6ZE, etcupdate 
didn't work as it had previously:

dreamer: {3} su
Password:
dreamer: {1} /home/current/src/etc/postinstall -s /home/current/src -d // fix postinstall defaults mtree rc makedev obsolete
[...]

dreamer: {2} etcupdate -s /home/current/src/etc
*** Creating /tmp/temproot
*** Populating /tmp/temproot from /home/current/src/etc
ERROR: 'MACHINE' and 'MACHINE_ARCH' must be set in environment

Tried rebooting to ensure the kernel and userland matched, same result.
This sequence had worked for some months now, so it's a definite change 
that is not reflected in the man page....
