Reparenting would require diving inside this lot:
/* * pointers to (original) parent process, youngest child, younger sibling, * older sibling, respectively. (p->father can be replaced with * p->p_pptr->pid) */ struct task_struct *p_opptr, *p_pptr, *p_cptr, *p_ysptr, *p_osptr; struct list_head thread_group;
plus maybe rewriting pgrps, sessions, gids, etc. Challenging.
Plus it would mean that the kernel requires, for its correct operation, that process "1" is a child reaper.
