Sorry? glibc has absolutely no problems with /etc/localtime being link
into /run, /var or whatever else (nor has it problems with this file
being normal file and not a link) as long as content of this file is
valid time zone definition. The only piece of software that has problem
with it is systemd. So may be you should stop finger pointing and simply
explain why *systemd* demands that /etc/localtime be specific symlink.

And yes, in current world this is state and not persistent config. When
I travel into another time zone I change state of my system for this
timezone. Just like DNS server address. Guess what? There is DHCP option
for time zone ... so how is it different from DNS server address?
