I've written this article: https://blog.apnic.net/2017/11/09/ce-vendors-share-thoughts-ipv6-support/
And somebody suggested having dual flash/boot, to avoid issues if there is a power outage, etc.
And somebody suggested me to look at OSTree.
How feasible will be to have that in LEDE ?
I know we have failsafe mode, but it will be nice, specially for allowing remote upgrades, when using LEDE in ISPs, to have this feature. Not sure if is so easy to integrate in LEDE and what are the additional memory requirements, or if it requires the boot code to be updated, etc., if it will also allow incremental updates, etc., etc.
