..my /etc/cron.d/machine-id:
PATH=/bin:/usr/bin:/sbin:/usr/sbin

# ..a new /etc/machine-id every minute... ;o)
* * * * * root  date |md5sum |cut -d" " -f-1 >/etc/machine-id |tee
  >/dev/null 2>&1

...keeps e.g. chromium from whining about:
"[20478:20478:0307/101807.205617:ERROR:browser_dm_token_storage_linux.cc(101)]
Error: /etc/machine-id contains 0 characters (32 were expected)"

ll /proc/sys/kernel/random/boot_id /etc/hostid /etc/machine-id \
/var/lib/dbus/machine-id /var/db/dbus/machine-id
