source: branches/2.2.2/mindi-busybox/coreutils/chown.c @ 1247

Last change on this file since 1247 was 821, checked in by Bruno Cornec, 14 years ago

Addition of busybox 1.2.1 as a mindi-busybox new package
This should avoid delivering binary files in mindi not built there (Fedora and Debian are quite serious about that)
