But again that's not okay for all testcases.  If I want to do SCSI
tests, I cannot write them in shell scripts because qemu-jeos does not
have sg3_utils.

Even libos would not help; relying on sg3_utils means that the client is
a completely clear reimplementation.  I don't care about the extra trips
to the SCSI specs that sg3_utils would save.  The problem is that since
qtest cannot run on real hardware, I don't have confirmation that I
didn't misinterpret the standards.  Writing all bits of the testsuite
makes it likely to have the same misinterpretations in both the tested
code and the tests, even if I try to write the tests from scratch with
only the spec in front of me.

I don't care about udev.  But even just binutils+GCC+kernel+uclibc is
not as easy if you care about dozens of architectures.
