See bug 40659 - but this is something different. After portage being hosed by 2.0.50 any attempt after following README.RESCUE to reinstall an earlier portage results in: --------------------------- ACCESS VIOLATION SUMMARY --------------------------- LOG FILE = "/tmp/sandbox-portage-2.0.50_pre22-24938.log" open_wr: /etc/group open_wr: /etc/passwd -------------------------------------------------------------------------------- This happens with every version available. I haven't done anything to change the perms on /etc/group or /etc/passwd, if that's what this is about, which are: # ls -l passwd -rw-r--r-- 1 root root 2209 Dec 29 10:21 passwd free /etc # ls -l group -rw-r--r-- 1 root root 751 Jan 12 11:19 group Reproducible: Always Steps to Reproduce: 1. install bad portage-2.0.50 2. run portage-rescue-2.0.47-r10-x86.tbz2 3. emergy sync then attempt to emerge any portage # emerge info Portage 2.0.47-r10 (default-x86-1.4, gcc-3.2.3, glibc-2.3.2-r9) ================================================================= System uname: 2.6.2-rc1-gentoo i686 AMD Athlon(tm) XP 2500+ GENTOO_MIRRORS="http://gentoo.oregonstate.edu/ http://distro.ibiblio.org/pub/Linux/distributions/gentoo" CONFIG_PROTECT="/etc /var/qmail/control /usr/kde/2/share/config /var/bind /usr/X11R6/lib/X11/xkb /usr/kde/3.1/share/config /usr/kde/3/share/config /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/ /usr/share/config" CONFIG_PROTECT_MASK="/etc/gconf /etc/env.d" PORTDIR="/usr/portage" DISTDIR="/usr/portage/distfiles" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR_OVERLAY="" USE="x86 oss apm avi crypt cups encode foomaticdb gif gtk2 jpeg kde gnome libg++ mad mikmod mpeg ncurses nls pdflib png quicktime spell truetype xml2 xmms xv zlib gdbm berkdb slang readline arts tetex svga tcltk java guile mysql X sdl gpm tcpd pam libwww ssl perl python esd imlib oggvorbis gtk qt motif opengl mozilla cdr" COMPILER="gcc3" CHOST="i686-pc-linux-gnu" CFLAGS="-O2 -mcpu=i686 -pipe" CXXFLAGS="-O2 -mcpu=i686 -pipe" ACCEPT_KEYWORDS="x86" MAKEOPTS="-j2" AUTOCLEAN="yes" SYNC="rsync://rsync.gentoo.org/gentoo-portage" FEATURES="sandbox ccache"
Can get around this with FEATURES="-sandbox" in make.conf. I assume that the sandbox is actually a Really Good Thing, so hope this will be fixed.
carpaski has some new portage rescue tarballs on his dev.gentoo.org site, which if I'm not mistaken replace those in /usr/portage/sys-apps/portage/files/.
There is a portage-2.0.50-r1 rescue tarball available. See the readme.
