On the naming issue, see my other message from a few days ago. Concerning
the added complexity and the need-for-cleanup in init/do_mounts_initrd.c
and init/main.c, I have added the following comment:

In the near future, the fs-external callers of ksys_dup{,3}() should be
converted to call do_dup2() directly. Then, ksys_dup{,3}() can be moved
within sys_dup{,3}() again.
