USE flags

• debug - Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see http://www.gentoo.org/proj/en/qa/backtraces.xml
• elibc_glibc - ELIBC setting for systems that use the GNU C library
• ipv6 - Adds support for IP version 6
• make-symlinks - Create all the appropriate symlinks in /bin and /sbin.
• math - Enable math support in gawk (requires libm)
• mdev - Create the appropriate symlink in /sbin and install mdev.conf and support files
• pam - Adds support for PAM (Pluggable Authentication Modules) - DANGEROUS to arbitrarily flip
• savedconfig - Use this to restore your config from /etc/portage/savedconfig ${CATEGORY}/${PN}. Make sure your USE flags allow for appropriate dependencies
• selinux - !!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur
• sep-usr - Support a separate /usr without needing an initramfs by booting with init=/bbinit
• static - !!do not set this during bootstrap!! Causes binaries to be statically linked instead of dynamically
