Here's a few ways to do it: # # (1) Emerge busybox with FEATURES=keepwork so the work directory won't # get erased afterwards. 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. # ################################################################################ #SNAPSHOT=20040726 SNAPSHOT="" DESCRIPTION="Utilities for rescue and embedded systems" HOMEPAGE="http://www.busybox.net/" if [[ -n ${SNAPSHOT} ]] ; then MY_P=${PN} SRC_URI="http://www.busybox.net/downloads/snapshots/${PN}-${SNAPSHOT}.tar.bz2" else MY_P=${PN}-${PV/_/-} SRC_URI="http://www.busybox.net/downloads/${MY_P}.tar.bz2" fi LICENSE="GPL-2" SLOT="0" KEYWORDS="alpha ~amd64 arm ~hppa ia64 ~m68k ~mips ~ppc ~ppc64 ~s390 ~sh sparc x86" IUSE="debug make-symlinks pam selinux static" RESTRICT="test" DEPEND="selinux?
