Add a definition like ROOT=/my/root/path to the +# start of the line if you're installing to somewhere else than the root +# directory. This command will save the default configuration to +# ${PORTAGE_CONFIGROOT} (or ${ROOT} if ${PORTAGE_CONFIGROOT} is not +# defined), and it will tell you that it has done this. Note the location +# where the config file was saved. +# +# FEATURES=keepwork USE=savedconfig emerge busybox +# +# (2) Go to the work directory and change the configuration of busybox using its +# menuconfig feature. +# +# cd /var/tmp/portage/busybox*/work/busybox-* +# make menuconfig +# +# (3) Save your configuration to the default location and copy it to the +# one of the locations listed in /usr/portage/eclass/savedconfig.eclass +# +# (4) Emerge busybox with USE=savedconfig to use the configuration file you +# just generated. +# +################################################################################ +# +# (1) Alternatively skip the above steps and simply emerge busybox without +# USE=savedconfig. +# +# (2) Edit the file it saves by hand. ${ROOT}"/etc/portage/savedconfig/${CATEGORY}/${PF} +# +# (3) Remerge busybox as using USE=savedconfig. +# +################################################################################ + +DESCRIPTION="Utilities for rescue and embedded systems" +HOMEPAGE="http://www.busybox.net/" +if [[ ${PV} == "9999" ]] ; then + MY_P=${PN} + EGIT_REPO_URI="git://busybox.net/busybox.git" + inherit git-2 +else + MY_P=${PN}-${PV/_/-} + SRC_URI="http://www.busybox.net/downloads/${MY_P}.tar.bz2" + KEYWORDS="~alpha ~amd64 ~arm ~hppa ~ia64 ~m68k ~mips ~ppc ~ppc64 ~s390 ~sh ~sparc ~x86 ~amd64-linux ~x86-linux" +fi + +LICENSE="GPL-2" +SLOT="0" +IUSE="ipv6 livecd make-symlinks math mdev ntpd -pam selinux sep-usr +static sysklogd systemd watchdog" +RESTRICT="test" + +RDEPEND="!static?
