I remember Heise reporting on that a few years back. Probably correct. The machine is approx 4 years old. It's also a 32-bit kernel, because back then... 1) Flash didn't work on 64-bit kernels without jumping through flaming hoops This never bothered me *that* much. You needed, what, nspluginwrapper? I don't remember much what my experience was like, I think it was merely annoying, but it's been years. Looking at my merge history, I used it from March 2007 (my first Gentoo/Sabayon install) till December 2008. Then I see I had it installed again from June to September 2010. So first of all, it looks like I was using the netscape-flash alpha releases that had 64 bit support (in tree since November 2008), and genlop verifies this. What happened in 2010: Adobe didn't manage to deliver a 64 bit version of Flash 10.1. I see the merge and unmerge dates of nspluginwrapper coincide with upgrading to adobe-flash 10.1 and then to 10.2, respectively. But hey, it looks like Flash is going the way of the Dodo, so hooray! 2) Wine required either multilib support or straight 32-bit linux My box is around 6 years old now (bought at the beginning of my studies with my earnings from (semi-)compulsory military service). I still went with Gentoo amd64, even though 64bit support was still... incomplete. I don't regret it, either. Gentoos emul-linux-* packages tended to be complete enough for my needs, and I could even work with my student edition of Matlab. Of course, everybody has their own requirements to consider, and mine didn't dictate a 32 bit OS. On a new machine today, I'd probably install 64-bits, unless there was some weird requirement for 32-bits. I don't push my machines that hard, and they generally last. I've mostly bought Dell desktops (including this one). The exception was was because Dell wasn't offering a machine with 8 gigs of RAM when I wanted it. The fact that the local guy also had a motherboard with a PS/2 keyboard connector was another plus. I have a couple of of IBM clickety-clack 104-keyboard specials that were being thrown out by my former employer a few years ago. I love them. I've bought a couple of ASUS notebooks as well. Hell, my workplace installs 64 bit systems by default (and has been for a while now). If that's not a sign... well, OK, it's a research institution, but still ;) . I only ever owned this one computer of mine, I could never afford a replacement or a laptop (argh!), only upgrades every now and then, like recently buying 2x2GB RAM to replace my previous 4x512MB - and it's DDR2, so 3 times as expensive as the same amount of DDR3 :( (well, in the store, at least: about 60 € vs. 20 €). I won't be buying more RAM without replacing my mainboard and CPU, even though my current mainboard supports up to 8GB, but this upgrade was definitely worth it. -- Marc Joliet -- People who think they know everything really annoy those of us who know we don't - Bjarne Stroustrup signature.asc Description: PGP signature

I just discovered one for xfce4: emerge tumbler No other config. Really cool result. In general, emerging an add-on for an environment will pull in the environment as a dependancy. Similar to your setup, back when I used blackbox, emerging bbkeys would pull in blackbox as a dependancy. My setup takes a little a little setting up, but saves a lot of work when setting up a new kernel. I run with 2 kernels available... 1) Production 2) Experimental Sometimes they're identical. Here's a simplified version of my /etc/lilo.conf with the comment lines stripped out lba32 boot = /dev/sda map = /boot/.map install = /boot/boot-menu.b menu-scheme=Wb prompt timeout=150 delay = 50 image = /boot/kernel-3.0-production root = /dev/sda5 label = Production read-only # read-only for checking append = noexec32=on image = /boot/kernel-3.0-experimental root = /dev/sda5 label = Experimental read-only # read-only for checking append = noexec32=on This gives me a boot menu with Production and Experimental kernels to boot from. There are also 2 small scripts... /usr/src/makeover ***IMPORTANT*** The arch/x86 directory is specific to 32-bit i686 kernels. Adjust accordingly if you use a different architecture. #!/bin/bash make \ make modules_install \ cp arch/x86/boot/bzImage /boot/kernel-3.0-experimental \ cp System.map /boot/System.map-3.0-experimental \ cp .config /boot/config-3.0-experimental \ lilo /usr/src/promote #!/bin/bash cp /boot/System.map-3.0-experimental /boot/System.map-3.0-production cp /boot/config-3.0-experimental /boot/config-3.0-production cp /boot/kernel-3.0-experimental /boot/kernel-3.0-production lilo I build a new kernel by running ../makeover from /usr/src/linux. It does the make and overwrites the previous Experimental kernel, and runs lilo. It does not touch Production. After the Experimental kernel has been running trouble-free for a while, I promote it to Production, by running ../promote from /usr/src/linux. This copies the experimental kernel over the production kernel. At this point, they are identical. Having a previous working kernel to fall back to has saved me on a few occasions. Note; on a brand new install, lilo will come back with an error on the very first run of ../makeover, because there is no Production kernel found. The first time you run ../makeover, run ../promote immediately afterwards. This copies the Experimental kernel to Production, and satisfies lilo. -- Walter Dnes waltd...@waltdnes.org We are apparently better off trying to avoid udev like the plague.
