I forgot one thing: ------- snip ------- Python 3 profile-guided optimisation ----------------------------------------------- The python3 recipe now enables profile-guided optimisation; this requires a little extra build time in exchange for improved performance on the target at runtime, and is only enabled if the current MACHINE has support for user-mode emulation in QEMU (i.e. "qemu-usermode" is in MACHINE_FEATURES, which it is by default, so the machine configuration would need to have opted out for it not to be). If you wish to disable Python profile-guided optimisation regardless of the value of MACHINE_FEATURES, then ensure that PACKAGECONFIG for python3 does not contain "pgo". You could accomplish the latter using PACKAGECONFIG_pn-python3 = "pgo" at the configuration level or by setting PACKAGECONFIG using a bbappend for the python3 recipe. ------- snip ------- > BTW I think the section on postinstalls (from Richard's input) is a little > terse > and needs expansion - most importantly it needs to describe what actions the > user might need to take. I'll take care of this on review if nobody else does. So what I think we need here is to copy part of the "Using exit 1 to explicitly defer a postinstall script until first boot..." paragraph that's mentioned in the 2.5 migration section. Would it make sense to actually break this out to its own place in the documentation (on "Deferring postinstalls to first boot") and then link to that from both places? While I think of it, could you also move the _remove item that's in the "Bitbake Changes" section into the "Override Changes" section?
