On my laptop with eth0 and ath0 (wifi) interfaces setting the RC_NET_STRICT_CHECKING option to 'no' has no impact on the system at boot time. Even though only the lo interface is active, scripts (such as ntp-client) which 'need net' do not heed this and will fail when using my pcmcia wifi card because the pcmcia subsystem and ath0 interface are not up. This does not match the behavior in the /etc/conf.d/rc file comments: # no - This basically means that at least one net.* service besides net.lo # must be up. This can be used by notebook users that have a wifi and # a static nic, and only wants one up at any given time to have the # 'net' service seen as up. Checking my /etc directory finds no match for this setting actually being used anywhere except the splash/livecd-2005.0 script list_svc.sh. emerge --info Portage 2.0.51.22-r2 (default-linux/x86/2005.0, gcc-3.3.5-20050130, glibc-2.3.5- r0, 2.6.12-gentoo-r4 i686) ================================================================= System uname: 2.6.12-gentoo-r4 i686 Intel(R) Pentium(R) 4 CPU 2.00GHz Gentoo Base System version 1.6.13 ccache version 2.3 [enabled] dev-lang/python: 2.3.5 sys-apps/sandbox: 1.2.10 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, 1.9.5 sys-devel/binutils: 2.15.92.0.2-r10 sys-devel/libtool: 1.5.18-r1 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=pentium4 -fomit-frame-pointer -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.3/env /usr/kde/3.3/share /config /usr/kde/3.3/shutdown /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kd e/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/lib/mozilla/default s/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/splash /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -march=pentium4 -fomit-frame-pointer -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig ccache distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://gentoo.mirrors.pair.com http://ftp6.uni-erlangen.de/pub/m irrors/gentoo ftp://ftp6.uni-erlangen.de/pub/mirrors/gentoo ftp://vlaai.snt.ipv6 .utwente.nl/pub/os/linux/gentoo/ ftp://ftp.ipv6.uni-muenster.de/pub/linux/distri butions/gentoo ftp://vlaai.snt.ipv6.utwente.nl/pub/os/linux/gentoo/ ftp://ftp6.u ni-erlangen.de/pub/mirrors/gentoo http://gentoo.binarycompass.org http://vlaai.s nt.ipv6.utwente.nl/pub/os/linux/gentoo/" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 X a52 aac aalib acpi aim alsa apache2 apm arts avi bash-completion berk db bitmap-fonts bonobo bzlib cdparanoia cdr crypt cups curl dga directfb divx4li nux doc dvb dvd dvdr dvdread eds emboss encode esd ethereal evo fam fbcon flac f oomaticdb fortran ftp gd gdbm gif gnome gpm gstreamer gtk gtk2 gtkhtml guile ima gemagick imap imlib innodb ipv6 jabber java jpeg junit kde kerberos krb4 ldap li bg++ libwww live mad mikmod mmap motif mozilla mp3 mpeg msn mysql nas ncurses nl s ogg oggvorbis opengl oss pam pcmcia pda pdflib perl php pic png python qt quic ktime quotes radeon readline real rtc samba sdl shared slang spell sse sse2 ssl svga tcpd tetex tiff truetype truetype-fonts type1-fonts usb v4l v4l2 vorbis win 32codecs wxwindows xanim xine xinerama xml xml2 xmms xpm xv xvid xvmc yahoo zlib video_cards_radeon userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LANG, LC_ALL, LDFLAGS, LINGUAS
you didnt check all the files, it is used in rc services you also missed the comment just below what you quoted ... you have to set it to 'lo' not to 'no'
I did check all the files on my system in /etc and that option is not used except in /etc/splash/livecd-2005.0 I'm not sure what 'rc services' file you are refering to but I don't have it in /etc. Is it locate someplace else? I am using the latest stable baselayout 1.11.13. Option 'lo' is what it seems to be doing when I have it set to 'no' which is not correct. If I am reading this correctly 'no' would require either eth0 or ath0 to be up in addition to lo and that's not what's happening. # no - This basically means that at least one net.* service besides net.lo # must be up. This can be used by notebook users that have a wifi and # a static nic, and only wants one up at any given time to have the # 'net' service seen as up. # lo - This is the same as the 'no' option, but net.lo is also counted. # This should be useful to people that do not care about any specific # interface being up at boot. I appologize in advance if I a missing something obvious here. Perhaps I am looking in the wrong place for references to this variable (if it's not in /etc) but, in any event, the behaviour I am experiencing does not match the documented behaviour as specified in /etc/conf.d/rc
then your config files werent updated properly re-emerge baselayout with the --noconfmem
