There are places where they flap your WAN (PPPoE session for instance) every day to renumber you. I have personally experienced this. So it might be possible to do what you're saying but only writing partial information of the prefix, so skip writing lifetimes, and just keep the actual prefix. This is not what a typical DHCP server/client does today, it re-writes the file every time the lease is renewed so it knows about it. Some kind of compromise might be where a "hint" file is written and the only time this is re-written is when the prefix is changed. OpenWrt today stores most volatile things in /tmp which is just /tmpfs. This has the added disadvantage that after a reboot the LAN lease file is empty. -- Mikael Abrahamsson email: swmike@swm.pp.se
