It will help for us to rename earlier vs later, and syscallfs will be laborious, especially after we introduce an FSConfig type and need to declare a method name that differentiates from normal fs.FS. e.g. WithFS vs WithSysFS reads nicer than WithSyscallFS, and meanwhile sys is already a public package.
