klibc-utils: new applets: resume, nuke, minips

2017-08-18T17:15:29+00:00

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. function old new delta resume_main - 582 +582 packed_usage 31640 31712 +72 nuke_main - 28 +28 xstrtoull - 24 +24 applet_names 2646 2665 +19 applet_main 1532 1544 +12 applet_suid 96 97 +1 applet_install_loc 192 193 +1 applet_flags 96 97 +1 ------------------------------------------------------------------------------ (add/remove: 5/0 grow/shrink: 6/0 up/down: 740/0) Total: 740 bytes Signed-off-by: Denys Vlasenko
