I'm trying to make some nommu-friendly busybox-like tools, which means using
vfork() instead of fork(). This means that after I fork I have to exec in
the child to unblock the parent, and if I want to exec my current executable
I have to find out where it lives so I can feed the path to exec(). This is
nontrivial.
Worse, it's not always possible. If chroot() has happened since the program
started, there may not _be_ a path to my current executable available from
this process's current or root directories.
How about openning an fd to yourself at the beginning of execution, then calling
fexecve later?
