I realized some time ago that because I don't do closed=20 source and most common FLOSS has already been ported, the chance of me=20 needing 32-bit multilib was essentially nill -- with the exception of=20 grub/lilo since amd64 continues to boot in 16-bit legacy mode, for legacy= =20 reasons (as long as the pc/mbr disk format stays around, at least, I=20 understand EFI/GPT can handle direct 64-bit booting, or at least the 32- bit portion is EFI and it can load 64-bit directly), if I wanted to=20 continue actually compiling them from source. But what I'm doing here isn't exactly multilib, but much more literally,=20 taking advantage of the bi-arch/bi-bitness nature of amd64, to assemble a 32-bit image for my netbook on my generally WAY more powerful dual-dual- core amd64 machine. I'll continue to do all the Gentoo updates to the 32= - bit chroot on my main machine, and will likely eventually rsync the atom=20 to the 32-bit chroot image. Of course, I don't have to worry about that=20 immediately, and I'm not -- I'm simply building the image right now, I've= =20 not even figured out what my partition layout's going to be on the atom. = =20 Once I get most stuff installed, I'll copy everything to a USB drive,=20 setup grub and a temporary fstab on it, and boot from it on on the=20 netbook/atom. Once that's working correctly, I'll gdisk the atom's 120=20 gig hd, mkreiserfs or perhaps experiment with btrfs on it, then copy the=20 image over on to it, make it bootable, and go from there. Only after=20 /that's/ all working, and decide what I'm going to do with networking as=20 well, will I need to worry about updating, and since I use=20 FEATURES=3Dbuildpkg, I can simply copy the binpkgs to USB stick and=20 "sneakernet" them until it's convenient to setup rsync or some such. Of course that's going way beyond multilib, since it's fully imaged multi= - arch (tho I don't plan on ever making the 32-bit image on my main machine= =20 actually bootable -- I'd have to stick an entirely different mdraid=20 config in grub, then figure out the partition to point root=3D at, to do=20 that, and since I already have a second fully bootable 64-bit=20 installation snapshot as a backup, there's little point in making the 32- bit actually bootable on the main machine), but that's what's great about= =20 Gentoo and the 32-bit chroot feature documentation and support -- it's so= =20 flexible in that regard! =3D:^) So definitely, it's all about options, and how Gentoo makes so many more=20 of them reasonably easily available, especially compared to the standard=20 but relatively limited bindists. --=20 Duncan - List replies preferred.
