1The rcutorture scripting tools automatically create an initrd containing
2a single statically linked binary named "init" that loops over a
3very long sleep() call.  In both cases, this creation is done by
4tools/testing/selftests/rcutorture/bin/mkinitrd.sh.

6However, if you don't like the notion of statically linked bare-bones
7userspace environments, you might wish to press an existing initrd
8into service:

11cd tools/testing/selftests/rcutorture
12zcat /initrd.img > /tmp/initrd.img.zcat
13mkdir initrd
14cd initrd
15cpio -id < /tmp/initrd.img.zcat
16# Manually verify that initrd contains needed binaries and libraries.
