egrep -E
Isn't it redundant to say "egrep -E"? "egrep" is supposed to just be a shorter/alternative way of saying "grep -E". -- Luiji 03:43, 31 December 2014 (UTC)
 * According to grep(1), "egrep is the same as grep -E" and direct egrep invocation is deprecated. So changed "egrep" to "grep" in the article. -- 0x6177 17:30, 31 December 2014 (UTC)

file capabilities
Is there some documentation on USE="filecaps" actually needing DebugFS in kernel? I see DebugFS used for perf stats, but filecaps seems unrelated. Petteyg (talk) 19:16, 13 March 2015 (UTC)

Try: https://packages.gentoo.org/useflags/filecaps and: https://devmanual.gentoo.org/eclass-reference/fcaps.eclass/index.html --MiroR (talk) 19:52, 7 August 2016 (UTC)

very frustrating
I had a very frustrating time trying to get this working. I don't want to be all crappy criticism, so I'll come back after I have things working well. There are a lot of kernel options that are missing from this page. I found http://www.linux-kvm.org/page/Tuning_Kernel this little guide] that gave a lot more, but some of this seems to be outdated already. Also, this section needs to distinguish between the kernel config on the host & guest. I finally had to boot the livecd and carefully examine lspci, /proc/config.gz, etc. to figure out what it was doing 'right' and that my guest kernel was doing 'wrong'.

Further, I suspect that grub2 with --target=i386-qemu may be preferable (I haven't actually gotten it working yet), but I was baffled by the lack of documentation, OH MY FUCKING GOD! One of the reasons that I suspect that it may be preferable is that it will install on a device (or image file) that is not fdisk-ed, because you may just want to put a single file system on an image file. Grub2 does not like installing there, but it doesn't seem to mind if --target=i386-qemu. The flip side of this mystery I think I've figured out today -- when you start qemu, you can pass -bios xxx. But xxx isn't just "qemu", it wants a bios file! I had no fucking clue where that was, now I think it's /usr/share/qemu/bios.bin (ran qlist qemu|grep -i bios). I'll try this one out later.
