[yocto] (How) did you script bitbake/set up nightly builds?

[Alan Martinovic]

Fair enough, I gave an example with a simple workaround. :)

But you do have a point there, if I'm getting you answer right on a broader
level.
Is it something like this?

So if I wanted to automate i.e.:

. oe-init-build-env mybuild
bitbake -c cleanall failure_prone_package
bitbake failure_prone_package
bitbake foo #image build

It's fine to do it like this:

subprocess.call(". oe-init-build-env mybuild ; bitbake -c cleanall
failure_prone_package", shell=True)
subprocess.call(". oe-init-build-env mybuild ; bitbake failure_prone_package",
shell=True)
subprocess.call(". oe-init-build-env mybuild ; bitbake foo", shell=True)
