I basically don't care about the privacy aspect for now (it is more of
a lab setup, and my IPv4 address is static, and its PTR resolves to
something with my surname in it ;). At least at the moment I would
prefer shorter IPv6 addresses than can be constructed from the MAC,
even considering the possibility to "fake" the MAC to something
with many zeroes, using historic/obsolete MAC vendor ids with zeroes in
them etc., because identifying IPs at one glance seems very attractive
to me. Right now I want as short/as memorable IPv6 addresses as
possible.

This is not permanent, is it? What is the suggested way to make this
survive a reboot in Debian?
Thanks for your comprehensive reply!
