Description Tomas Dolezal 2012-08-21 07:39:57 EDT
Description of problem:
busybox 'du' applet reports different sizes with -h and -m parameters comparing to coreutils 'du' on small files

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. `dd if=/dev/zero of=/tmp/testfile.tmp bs=1128k count=1`
2. check `du -h /tmp/testfile.tmp` and analogically with busybox
3. compare results
Actual results:
 comparation of last line with -h parameter
	busybox			|	coreutils
>1.1M	/tmp/testfile.tmp	| 1.2M	/tmp/testfile.tmp

 comparation of last line with -m parameter
	busybox			|	coreutils
>1	/tmp/testfile.tmp	| 2	/tmp/testfile.tmp

Expected results:
busybox 'du' reports same sizes when approximating as coreutils 'du' does
Comment 2 Denys Vlasenko 2012-12-14 11:21:48 EST
Coreutils rounds sizes up, busybox rounds to nearest.

Not sure whether this needs to be fixed...

For now I added a comment in the upstream busybox source explaining this.
Comment 3 Denys Vlasenko 2015-10-15 15:26:51 EDT
Closing as WONTFIX. This doesn't look important.
