May this is not bug but feature, if so close it. 'emerge --sync' now need writable and executable permissions in PORTAGE_TMPDIR As I remember, previously (some month's ago) emerge --sync dont need to write or execute anything to PORTAGE_TMPDIR (that partition is mounted readonly and I remount it rw only when I updating some packages), but now, when I running emerge --sync it failed with error: $PORTAGE_TMPDIR/portage is not writable. Likely cause is that you've mounted it as readonly. and Can not execute files in $PORTAGE_TMPDIR Likely cause is that you've mounted it with one of the following mount options: 'noexec', 'user', 'users' Please make sure that portage can execute files in this directory. output of 'emerge --info': Portage 2.1.9.10 (hardened/linux/amd64, gcc-4.3.4, glibc-2.10.1-r1, 2.6.34-hardened-r6.den_m.hd x86_64) ================================================================= System uname: Linux-2.6.34-hardened-r6.den_m.hd-x86_64-Intel-R-_Core-TM-2_Quad_CPU_Q9400_@_2.66GHz-with-gentoo-2.0.1 Timestamp of tree: Thu, 07 Oct 2010 09:00:01 +0000 app-shells/bash: 4.0_p37 dev-lang/python: 2.6.4-r1 dev-util/cmake: 2.6.4-r3 sys-apps/baselayout: 2.0.1 sys-apps/openrc: 0.6.2 sys-apps/sandbox: 1.6-r2 sys-devel/autoconf: 2.13, 2.63-r1 sys-devel/automake: 1.8.5-r3, 1.10.3, 1.11.1 sys-devel/binutils: 2.18-r3 sys-devel/gcc: 4.3.4 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.6b sys-devel/make: 3.81 virtual/os-headers: 2.6.30-r1 (sys-kernel/linux-headers) ACCEPT_KEYWORDS="amd64 ~amd64" ACCEPT_LICENSE="* -@EULA PUEL googleearth" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=core2 -O2 -pipe -fomit-frame-pointer" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/X11/xkb /var/qmail/alias /var/qmail/control" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo" CXXFLAGS="-march=core2 -O2 -pipe -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" EMERGE_DEFAULT_OPTS="--quiet" FEATURES="assume-digests distlocks fixlafiles fixpackages news parallel-fetch protect-owned sandbox sfperms strict suidctl unknown-features-warn unmerge-logs unmerge-orphans userfetch" GENTOO_MIRRORS="http://distfiles.gentoo.org" LC_ALL="ru_RU.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" LINGUAS="en" MAKEOPTS="-j5" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/usr/src/portage" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X acpi amd64 bash-completion bzip2 cairo clamav cli cracklib cups cxx dbus dga dri expat fbcon fftw firefox gif gtk hal hardened iconv jabber javascript jpeg justify maildir mime minimal mmx modules mudflap multilib ncurses nls nptl offensive opengl openmp pam pdf pic plotutils png posix readline reflection samba session sockets spell sse sse2 ssl sysfs tcpd threads tiff truetype unicode urandom usb xcomposite xorg xosd xpm xv zlib" ALSA_CARDS="hda-intel" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ubx" INPUT_DEVICES="evdev keyboard mouse" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="en" RUBY_TARGETS="ruby18" USERLAND="GNU" VIDEO_CARDS="i810 intel" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CPPFLAGS, CTARGET, FFLAGS, INSTALL_MASK, LANG, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY
This is fixed in git: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=59b1c6e1d2f6010ffac296aae26955437a5b3b76 It's a regression from bug 336503.
This is fixed in 2.1.9.14 and 2.2_rc91.
