At the start of sysvinit the system tells me that the kernel is missing support for tmpfs, which it does not. Downgrading to app-shells/bash-3.1_p17 solved the issue. -- Portage 2.1.2_pre2-r9 (default-linux/x86/2006.1, gcc-4.1.1, glibc-2.5-r0, 2.6.18-gentoo i686) ================================================================= System uname: 2.6.18-gentoo i686 Genuine Intel(R) CPU L2400 @ 1.66GHz Gentoo Base System version 1.13.0_alpha1 Last Sync: Fri, 13 Oct 2006 06:00:01 +0000 ccache version 2.4 [disabled] app-admin/eselect-compiler: [Not Present] dev-java/java-config: 1.3.7, 2.0.30 dev-lang/python: 2.4.3-r4 dev-python/pycrypto: 2.0.1-r5 dev-util/ccache: 2.4-r6 dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.18.1 sys-devel/autoconf: 2.13, 2.60 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2 sys-devel/binutils: 2.17 sys-devel/gcc-config: 1.3.13-r4 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.17-r1 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=pentium-m -O2 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/X11/xkb" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/gconf /etc/java-config/vms/ /etc/revdep-rebuild /etc/terminfo /etc/texmf/web2c" CXXFLAGS="-march=pentium-m -O2 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig cvs digest distlocks fixpackages metadata-transfer parallel-fetch sandbox sfperms sign strict" GENTOO_MIRRORS="http://mirror.gentoo.no/ ftp://ftp.du.se/pub/os/gentoo ftp://trumpetti.atm.tut.fi/gentoo/ ftp://sunsite.informatik.rwth-aachen.de/pub/Linux/gentoo http://gentoo.oregonstate.edu" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 X a52 aac acpi alsa asf berkdb bitmap-fonts bluetooth browserplugin bzip2 cairo cli crypt cups dbus dga divx4linux dlloader dri dvd dvdread eds elibc_glibc exif fame firefox flac foomaticdb fortran gaim galago gdbm gif glitz gnome gpm graphviz gstreamer gtk hal input_devices_evdev input_devices_keyboard input_devices_mouse iproute2 ipv6 isdnlog java jpeg kdeenablefinal kdehiddenvisibility kernel_linux libg++ libnotify libsexy lzo mad matroska mjpeg mmx mmxext mng mono moznocompose moznoirc moznomail mozsvg mp3 mpeg ncurses nls nomotif nptl nptlonly nsplugin ogg oggvorbis opengl pam pam_console pcre pdf perl png ppds pppd python quicktime readline reflection samba session smp spl sse sse2 ssl startup-notification svg tcpd tetex theora tiff truetype truetype-fonts type1-fonts udev unicode usb userland_GNU video_cards_i810 vorbis win32codecs wmf xcb xml xml2 xorg xv xvid xvmc zlib" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, LINGUAS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY uberlord@gentoo.org 2006-10-13 02:06:06 0000 In bash 3.2 the binary operator =~ is broken. [[ "one two three" =~ "one (.*) three" ]] && echo $? ${BASH_REMATCH[1]} || echo $? bash 3.1_p17 gives 0 two bash 3,2 gives 1 The exact call in baselayout that is failing is this local filesystems=$(</proc/filesystems) if [[ ${filesystems} =~ "[[:space:]]tmpfs"$'\n' ]] ; then fs="tmpfs" else <work out ramfs, etc> fi baelayout-1.12 shouldn't be affected by this as we use these tests in 1.13 (currently alpha, unstable and p.masked) uberlord@gentoo.org 2006-10-13 02:18:05 0000 3.2 Changelog f. Quoting the string argument to the [[ command's =~ operator now forces string matching, as with the other pattern-matching operators. match="one (.*) three" [[ "one two three" =~ ${match} ]] && echo $? ${BASH_REMATCH[1]} || echo $? now gives 0 two in bash 3.2 That sucks I suppose we could do match="one (.*) three" [[ "one two three" =~ ${dummyvar:-one (.*) three} ]] && echo $? ${BASH_REMATCH[1]} || echo $? which works also, but that sucks too. Hmmmmmm uberlord@gentoo.org 2006-10-13 02:28:16 0000 Problem is under discussion here http://lists.gnu.org/archive/html/bug-bash/2006-10/msg00045.html dushistov@mail.ru 2006-10-13 23:03:39 0000 I have another problem with bash and baselayout, related with reboot and poweroff, after their run /sbin/reboot or /sbin/poweroff I got something INIT: no more processes left on runlevel and root filesystem not unmounted correctly, and machine was not rebooted, or halted, I have to do it manualy, downgrade to < bash-3.2 was solved the problem. baselayout 1.12.5-r2 bash 3.2 pva@gentoo.org 2006-10-16 11:22:46 0000 Although this bug is only about =~ semantics, I'd like to note (just not to forgive about this) that there are some other problems with bash-3.2. Fex, compilation of kate and some other packages became broken. And I have not checked but may be this error also exist: http://lists.gnu.org/archive/html/bug-bash/2006-10/msg00046.html vapier@gentoo.org 2006-10-16 17:06:19 0000 the KDE issue is tracked in another bug ... it's a different issue so it gets a different bug uberlord@gentoo.org 2006-11-02 02:31:20 0000 baselayout-1.12.6 works with all bash versions.
