I'm not sure what's up with this update, but it hosed up the default
behavior of cpio.

It appears now that -o won't do the same things that it used to:

+ cd /
+ find -x .
+ egrep -v '^\.(/snap|/usr/sup|/boot/kernel/kernel
\.[[:alpha:]_]+\.[[:digit:]]+|/boot/kernel/kernel
\.old|/etc/start_if.*|/etc/ssh/ssh_host_.*key|/etc/hostid|/etc/(master.passwd|passwd|spwd.db|pwd.db))'
+ '[' -n '' ']'
+ '[' 7 = 4 ']'
+ '[' -n '' -a -z '' ']'
+ '[' -n /home/backup ']'
+ echo 'dumping / ...'
dumping / ...
+ cpio -o --quiet --format crc -O /home/backup/root.amd64.cpio
cpio: ./dev not dumped: minor number would be truncated
cpio: Removing leading `/' from member names
cpio: ./proc not dumped: minor number would be truncated
cpio: Removing leading `../' from member names

We've had to revert this change from our local tree, suggestions?
