Since init become dynamically linked, reroot appeared to be broken because init copies itself into a transient tmpfs mount to continue controlling execution right after the reboot(REROOT) syscall. Because the binary is dynamically linked, it cannot be properly executed. Provide a minimal static binary 'reroot_seed' embedded into the init as byte stream, which performs what the 'init -r' did, namely, the second phase reroot. For the static build of init as part of the /rescue crunch, keep the inline reroot code.
