Let me know your design...

This patch does using fork+execve() rather than calling UMH in pipe-coredump pass.
And coredump-pipe process is run as a child of get-dumped process.
Right ?

Doesn't this break existing solution actually used in distro ?

BTW, it's first time for me to see that _do_fork() is called outside from fork.c.
Isn't it better to add a new func in fork.c if we really need this ?

Thanks,
