I guess that's the price to pay for space reduction.... And I guess the fact that Teltonika bases their OS on OpenWrt is also because they manage to implement a dual-boot system with 16MB of flash, so there is some direct causal connection here, SPI-NOR still being much more reliable and cheaper than an eMMC which could fit Debian or whatever other OS... Anyway, does that warning also occur if CONFIG_MODULE_STRIPPED isn't selected? And is there any functional impact besides that warning? > >For my case, I just removed this patch and moved on.
