The 2022 embedded Linux update

Grumpily: home router vendors are often shipping 10 year old kernels, based on an obsolete, hacked up, vendor specific, unsupported version of openwrt.

Nobody knows how many "security" cameras are based on Linux because few in that market comply with the GPL.

It really is great that Linux has so much of the embedded market now, but "fossilized" FOSS is costing the world a lot in lost security, features, and developer interest.

Being there (at handhelds.org and MontaVista) I remember vividly the most compelling argument for linux in embedded in the 00s... was MMU support.
