source: branches/stable/mindi-busybox/coreutils/install.c @ 821

Last change on this file since 821 was 821, checked in by bruno, 13 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)
