During bootup, swapon is usually called two times: within /sbin/rc (runs first) and /etc/init.d/localmount. In my case, swap is already established by /sbin/rc. When running `/etc/init.d/localmount start`, I am getting the following error message: swapon: loop device /dev/loop2 already in use This is not a problem, just a cosmetic issue. As a fix, I suggest the following: # Swap on loopback devices, and other weirdnesses ebegin "Activating (possibly) more swap" /sbin/swapon -a &> /dev/null eend 0 within /etc/init.d/localmount.
no, that isnt going to happen post your `emerge info` and your /etc/fstab
grep swap /etc/fstab yields: /dev/evms/swap none swap sw,loop=/dev/loop2,encryption=AES256 0 0 As you can see, I am using loop-aes encrypted swap. For this purpose, I had to install a modified version of some util-linux tools (e.g. swapon) on my system (see http://loop-aes.sourceforge.net/loop-AES.README). In fact, the swapon error I mentioned is introduced by the loop-aes util-linux patch. So you can easily argue that you won't change Gentoo's /etc/init.d/localmount if Gentoo does not officially support loop-aes which seems to be the case since there is no stable marked version of loop-aes. That's fine with me; after all it's just a minor cosmetic issue and I can easily fix it on my system. The correct fix would be to "correct" the loop-aes util-linux patch. emerge --info yields: Portage 2.0.53 (default-linux/x86/2005.1, gcc-3.3.6, glibc-2.3.5-r2, 2.6.13-gentoo-r5 i686) ================================================================= System uname: 2.6.13-gentoo-r5 i686 AMD Athlon(tm) Processor Gentoo Base System version 1.6.14 ccache version 2.3 [enabled] dev-lang/python: 2.4.2 sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r6 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=athlon -pipe -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/lib/mozilla/defaults/pref /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/dvips/config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/ /usr/share/texmf/xdvi/ /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -march=athlon -pipe -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig ccache distlocks sandbox sfperms strict" GENTOO_MIRRORS="ftp://ftp.tu-clausthal.de/pub/linux/gentoo/ ftp://sunsite.informatik.rwth-aachen.de/pub/Linux/gentoo http://linux.rz.ruhr-uni-bochum.de/download/gentoo-mirror/ ftp://linux.rz.ruhr-uni-bochum.de/gentoo-mirror/ http://ftp.uni-erlangen.de/pub/mirrors/gentoo ftp://ftp.uni-erlangen.de/pub/mirrors/gentoo http://gentoo.osuosl.org/" LANG="de_DE@euro" LINGUAS="de" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="3dnow X Xaw3d a52 aac aalib accessibility acl acpi aim alsa apache2 apm arts audiofile avi bash-completion bcmath berkdb bitmap-fonts bluetooth bzip2 calendar caps cdb cdparanoia cdr cpdflib crypt cscope cups curl curlwrappers dbm dbus dedicated dga dio directfb doc dts dv dvb dvd dvdr dvdread eds emacs emboss encode esd ethereal examples exif expat fam fastcgi fbcon ffmpeg fftw flac flash flatfile foomaticdb fortran freetds ftp gd gdbm geoip gif ginac glut gmp gnome gnutls gphoto2 gpm gps gstreamer gtk gtk2 guile hal hardened hardenedphp howl hyperwave-api icc iconv icq idn ieee1394 imagemagick imap imlib innodb iodbc ipv6 jabber jack java javascript joystick jpeg kde kdeenablefinal kerberos krb4 ladcca lcms ldap leim lesstif libcaca libg++ libgda libwww lirc lm_sensors mad maildir matroska matrox mcal mcve memlimit mhash mikmod milter mime ming mmap mmx mng mono motif mozilla mp3 mpeg mpi msession msn mule mysql mysqli nas ncurses netcdf nls nocd nptl offensive ofx ogg oggvorbis openal opengl osc oscar oss pam pcntl pcre pda pdflib perl pfpro php plotutils png portaudio posix ppds python qdbm qt quicktime radius readline recode ruby samba sasl scanner sdl session sharedext sharedmem shorten simplexml skey slang slp smartcard sndfile snmp soap sockets socks5 sox speex spell spl sqlite ssl svg svga tcltk tcpd tetex theora threads tidy tiff tokenizer truetype truetype-fonts type1-fonts udev usb v4l vcd vhosts videos vorbis wddx win32codecs wmf wxwindows x86 xface xine xml xml2 xmlrpc xmms xpm xprint xsl xv xvid yahoo yaz zeo zlib linguas_de userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LC_ALL, LDFLAGS, PORTDIR_OVERLAY

After emerging the latest Gentoo util-linux ebuild, everything is fine. Thanks for the information. In fact, I did not become aware of Gentoo's util-linux supporting loop-aes.
that works too ;)
