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.

452cc1d9bd ash: [PARSER] Catch variable length expansions on non-existant specials 
Upstream commit:

    Date: Thu, 30 Oct 2014 11:53:35 +0800
    [PARSER] Catch variable length expansions on non-existant specials

    Currently we only check special variable names that follow directly
    after $ or ${.  So errors such as ${#&} are not caught.  This patch
    fixes that by moving the is_special check to just before we print out
    the special variable name.
