Denys Vlasenko ab77e81a85 klibc-utils: new applets: resume, nuke, minips 
minips is a pure alias to ps, just in case someone needs 100% klibc-utils compat.
nuke is a primitive version of "rm -rf" without options and error checks. ~30 bytes.

resume is a tool for initramfs which resumes from a given block device.
