You're overriding what "qemu my_pc" means.  "qemu my_pc" create a QEMU
vm with 128m of memory and -hda my_pc with the default network card.

"qemu -c my_pc/config" only has one meaning: read command line arguments
from "my_pc/config".

Your suggested syntax may be simpler for your particular use-case, but
it makes QEMU much more difficult to understand for every other user.
