Product: buildroot
Version: unspecified
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: mzweerspenko+bugzilla at gmail.com
CC: buildroot at uclibc.org
Target Milestone: ---

After clean build (no stress-ng and no attr)
user at user:/data/buildenv/buildroot$ cp output/target/bin/busybox output/target/bin/busybox_orig
user at user:/data/buildenv/buildroot$ sha256sum output/target/bin/busybox* fcdab0b55c09f00e85421dd1ad7249dd49a4a0f22753021ee506aa063e56e44c output/target/bin/busybox fcdab0b55c09f00e85421dd1ad7249dd49a4a0f22753021ee506aa063e56e44c output/target/bin/busybox_orig

After adding and building with stress-ng and attr packages

user at user:/data/buildenv/buildroot$ sha256sum output/target/bin/busybox* d088445e2aa618140b000dc1449481adb621ec6485d962bd08dc0539eac0ac84 output/target/bin/busybox fcdab0b55c09f00e85421dd1ad7249dd49a4a0f22753021ee506aa063e56e44c output/target/bin/busybox_orig

user at user:/data/buildenv/buildroot$ ls -l output/target/bin/busybox*
-rwxr-xr-x 1 remotenerd remotenerd 9800 mei 4 08:38
output/target/bin/busybox
-rwxr-xr-x 1 remotenerd remotenerd 535524 mei 4 08:38 output/target/bin/busybox_orig

<Buildlog>
Warning: target file "./bin/busybox" is touched by more than one package:
[u'busybox', u'attr']
</Buildlog>

<Symptom>

As attr uses the zero argument for its help page it results in an confusing error message

[    2.327505] Freeing unused kernel memory: 1024K
[    2.355884] usb 2-1: new high-speed USB device number 2 using ci_hdrc
Usage: init {-n name} [-v value] [-h] file...
       init {-x name} [-h] file...
Try `init --help' for more information.
[    2.386012] Kernel panic - not syncing: Attempted to kill init!
exitcode=0x00000200
[    2.386012]
[    2.386027] CPU1: stopping
[    2.386036] CPU: 1 PID: 

</Symptom>
Tested on an NXP IMX7D

<speculation>
Other packages that are also supplied by busybox may lead to similar results. </speculation>
