It provides minimalist replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. BusyBox provides a fairly complete POSIX environment for any small or embedded system." -HOMEPAGE = "http://www.busybox.net" +HOMEPAGE = "https://www.busybox.net" BUGTRACKER = "https://bugs.busybox.net/" DEPENDS += "kern-tools-native virtual/crypt" @@ -431,6 +431,32 @@ fi d.prependVar('pkg_postinst_%s' % pkg, postinst) } +pkg_postinst_${PN}_prepend () { + # Need path to saved utils, but they may have be removed on upgrade of busybox + # Only use shell to get paths.
