I worry there's a lot of "make it compile, deal with it later" in here rather than unwinding so that $X works with CMDLINE disabled or we truly must have CMDLINE. Perhaps it would be better to start with to take one of the platforms that enables say networking in SPL, where we functionally don't have a cmdline, and make that build with CMDLINE off. Having *PL build and link and work with CMDLINE disabled would possibly save some space too, which is always a good thing there. -- Tom
