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.

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 toolchain scripts/mcm-buildall.sh patches musl to fix this." #define HELP_toybox_uid_usr "When commands like useradd/groupadd allocate user IDs, start here." |
