Busybox uses the fork(2) system call for the standard init(8) utility.
I've been told this works on uClinux in conjuction with uClibc. If I
understand correctly that uClinux doesn't provide fork(2), how does
this work? Does fork(2) return ENOSYS, or is it blindly remapped to

I'm using an ARM7 processor with no MMU.

Please cc me in your reply. Thanks!
