 #define HELP_toybox_force_nommu "When using musl-libc on a nommu system, you'll need to say \"y\" here\nunless you used the patch in the mcm-buildall.sh script. You can also\nsay \"y\" here to test the nommu codepaths on an mmu system.\n\nA nommu system can't use fork(), it can only vfork() which suspends\nthe parent until the child calls exec() or exits. When a program\nneeds a second instance of itself to run specific code at the same\ntime as the parent, it must use a more complicated approach (such as\nexec(\"/proc/self/exe\") then pass data to the new child through a pipe)\nwhich is larger and slower, especially for things like toysh subshells\nthat need to duplicate a lot of internal state in the child process\nfork() gives you for free.\n\nLibraries like uclibc omit fork() on nommu systems, allowing\ncompile-time probes to select which codepath to use. But musl\nintentionally includes a broken version of fork() that always returns\n-ENOSYS on nommu systems, and goes out of its way to prevent any\ncross-compile compatible compile-time probes for a nommu system.\n(It doesn't even #define __MUSL__ in features.h.) Musl does this\ndespite the fact that a nommu system can't even run standard ELF\nbinaries (requiring specially packaged executables) because it wants\nto force every program to either include all nommu code in every\ninstance ever built, or drop nommu support altogether.\n\nBuilding a scripts/mcm-buildall.sh toolchain patches musl to fix this."
