I1 becomes a DNS query to a random popular domain (A/AAAA) instead of the
shared icloud.com response every key carried. The format sticks to tags both
the kernel module and amneziawg-go accept and is checked before awg1.conf is
written: a bad I1 fails the whole awg-quick up. With KEEP_DATA=y the old I1
is kept, or generated if missing — the server never checks it, old keys keep
their own.
MTU is picked from 1320–1376 (AWG_MTU overrides) and kept on reinstall.
awg-ctrl now reads MTU from awg1.conf for vpn:// keys instead of a constant.
