On downgrading from sys-fs/reiserfsprogs-3.6.20 (because it was added to package.mask) to 3.6.19, /sbin no longer contains fsck.reiserfs, which I think should be symlinked to /sbin/reiserfsck. emerge --info Portage 2.1.2_rc4-r1 (default-linux/x86/2006.1/desktop, gcc-4.1.1, glibc-2.5-r0, 2.6.19-gentoo-r2 i686) ================================================================= System uname: 2.6.19-gentoo-r2 i686 Intel(R) Pentium(R) 4 CPU 3.20GHz Gentoo Base System version 1.12.8 Last Sync: Thu, 28 Dec 2006 20:50:01 +0000 dev-java/java-config: 1.3.7, 2.0.31 dev-lang/python: 2.4.4 dev-python/pycrypto: 2.0.1-r5 sys-apps/sandbox: 1.2.18.1 sys-devel/autoconf: 2.13, 2.61 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10 sys-devel/binutils: 2.17 sys-devel/gcc-config: 1.3.14 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.19 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=nocona -mtune=nocona -pipe -ggdb" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/X11/xkb /usr/share/config /var/bind" 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="-O2 -march=nocona -mtune=nocona -pipe -ggdb" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks installsources metadata-transfer parallel-fetch sandbox sfperms splitdebug strict" GENTOO_MIRRORS="http://linux.rz.ruhr-uni-bochum.de/download/gentoo-mirror/ http://ftp.du.se/pub/os/gentoo http://mirrors.sec.informatik.tu-darmstadt.de/gentoo/ http://pandemonium.tiscali.de/pub/gentoo/ http://gentoo.mirror.solnet.ch http://gentoo.blueyonder.co.uk" LANG="en_GB.UTF-8" LC_ALL="en_GB.UTF-8" LINGUAS="en_GB" 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" PORTDIR_OVERLAY="/usr/local/portage /usr/portage/local/layman/sunrise /usr/portage/local/layman/musicbrainz" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="x86 X a52 aac aalib acl acpi aim alsa alsa_cards_hda-intel alsa_pcm_plugins_adpcm alsa_pcm_plugins_alaw alsa_pcm_plugins_asym alsa_pcm_plugins_copy alsa_pcm_plugins_dmix alsa_pcm_plugins_dshare alsa_pcm_plugins_dsnoop alsa_pcm_plugins_empty alsa_pcm_plugins_extplug alsa_pcm_plugins_file alsa_pcm_plugins_hooks alsa_pcm_plugins_iec958 alsa_pcm_plugins_ioplug alsa_pcm_plugins_ladspa alsa_pcm_plugins_lfloat alsa_pcm_plugins_linear alsa_pcm_plugins_meter alsa_pcm_plugins_mulaw alsa_pcm_plugins_multi alsa_pcm_plugins_null alsa_pcm_plugins_plug alsa_pcm_plugins_rate alsa_pcm_plugins_route alsa_pcm_plugins_share alsa_pcm_plugins_shm alsa_pcm_plugins_softvol apache2 arts audiofile avi bash-completion berkdb bitmap-fonts bluetooth bonobo browserplugin bzip2 bzlib cairo caps cdparanoia cdr cjk cli cracklib crypt cups curl dbus dlloader doc dri dts dvd dvdr dvdread eds elibc_glibc emacs emboss encode esd ethereal examples exif expat fam fbcon ffmpeg firefox flac foomaticdb fortran gcj gd gdbm gif glut gmp gnome gnutls gphoto2 gpm graphviz gstreamer gtk gtk2 gtkhtml guile hal iconv icq idn ieee1394 imagemagick imlib input_devices_evdev input_devices_keyboard input_devices_mouse ipv6 isdnlog jabber jack java javascript jbig jce jpeg jpeg2k junit kde kdehiddenvisibility kernel_linux lcms leim libg++ libgda libnotify libsamplerate linguas_en_GB lm_sensors logrotate lua mad matroska mbox mikmod milter mime mmap mmx mng mono mp3 mpeg mpi msn ncurses nls nptl nptlonly nsplugin offensive ogg oggvorbis openal opengl oscar oss pam pcntl pcre pdf perl png postgres ppds pppd profile python qt3 qt4 quicktime readline recode reflection ruby sdl seamonkey session sharedmem sndfile snmp sockets sox speex spell spl sse sse2 ssl svg sysvipc tcl tcltk tcpd tetex theora threads tiff tk truetype truetype-fonts type1-fonts udev uicktime unicode usb userland_GNU v4l video_cards_fbdev video_cards_radeon video_cards_vesa vim-syntax vorbis win32codecs wmf wxwindows x264 xface xine xml xml2 xorg xv xvid yahoo zlib" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LDFLAGS, PORTAGE_RSYNC_EXTRA_OPTS
Not downgrade related, this version simply doesn't create the symlinks at all (you can check in /var/db/pkg/sys-fs/reiserfsprogs-3.6.19/CONTENTS)
added back in symlinks with 3.6.19-r1 ... i was looking at 3.6.20 and thought they werent needed any longer, but that's only true for 3.6.20, not 3.6.19
