The links under Resources/Accessing and Contributing to Source seems to only link to the Chromium OS and not the Container-Optimized OS.
The actual feedback
I noticed that the "cpu MHz" entry under /proc/cpuinfo on cos-dev is 0, compared to cos-stable which is 2600.000.
While I realise that dev obviously means "under development", I haven't been able to find an issue tracker on the project, and it's causing my docker build to fail, because the "cpu mhz" information isn't propagated properly to the container, so a process that requires the information breaks.
This wasn't a problem when I was running with cos-stable, but I needed v17.07+ of Docker, and cos-stable runs v17.03.
Thank you for reporting this! As of now we don't have public issue tracker,you can reach us at any of mentioned way listed here.
I have not been able to reproduce this on latest COS image which is "cos-dev-70-11021-11-0", you could retry with latest. Here is the command/output I've tried with instance created from latest cos-dev image:
