Re: [gentoo-user] Any booby-traps with AMD64?
I've got my bright shiney (would you believe dull beige-coloured?) new toy, and I'm working on the install now. A few anxious newbie moments... - when I tried unscrewing the dialup-modem-connector cable from my old machine, I ended up with the thumbscrew in my hand, and the modem connector still firmly connected... oops. It took several minutes of screwing in, unscrewing, and wiggling around to get it out. I have used my dialup account on occasion when my ADSL ISP was down so I do want to keep the dialup option. I'll remove the thumbscrews before inserting the connector onto my new machine. - the install CD couldn't find /dev/hda ... because the SATA drive shows up as /dev/sda (dohhh) - when I first tried chrooting, it failed with an Exec format error. After a bit of googling, I finally figured out that I had grabbed my ***32-bit X86*** Gentoo 2005.1 install CD and tried to install the 64-bit version (dohhh). Download and burn the AMD64 install ISO, wipe /dev/sda1 and restart. I've gone with 12 gigs for /dev/sda1, 2 gigs for /dev/sda5 (swap), and the rest of the drive is /dev/sda6, which will be mounted as /home. I'm using ReiserFS, as the Gentoo AMD64 guide seems a bit dated, with references to 2004.3. The references to 32-bit compilation are somewhat confusing. It looks like I have two choices... 1) Building my system with the multilib flag and *MANUALLY* building stuff with the m32 flag. Stuff should probably go to /usr/local. 2) A complete chrooted environment into which I do a full-blown 32-bit X86 (*NOT* AMD64) install. -- Walter Dnes [EMAIL PROTECTED] My musings on technology and security at http://tech_sec.blog.ca -- gentoo-user@gentoo.org mailing list
Re: [gentoo-user] Any booby-traps with AMD64?
On my last few installs I have used LVM2: magic as it means you can easily and transparently resize partitions and add new drives with minimal downtime. Partition size choices are no longer such a limiting factor. Highly recommended.

I've been running resierfs and xfs for well over a year with zero
problems.
I intend to use the following partition layout...
- /8 gigs
- swap 2 gigs
- /var 8 gigs
- /home gets the rest of the drive. There'll be tons of my garbage
under /home/misc. /usr/local and /opt will be symlinks on / with
the actual files sitting in /home/misc/local and /home/misc/opt.
8GB for / is probably OK, I have that size for /usr, with /var and .opt
mounted on /usr/{var,opt} and it's around 75% full (/ is ~150MB).
symlinks for partitions always seem kludgy to me, I prefer to mount on
the directory with the bind option, I use
/usr/var /var auto bind 0 0
in /etc/fstab.
This layout reflects my experiences from my Windows and Redhat days.
Keep the OS on its own partition, so you can blow away and re-install or
install the next version as required.
There is no next version with Gentoo, so this doesn't really apply.
Even if you did feel some odd need to reinstall, it's no big deal to tar
up /usr/local before doing so.

Gentoo on AMD64 is the only way to go AMD64, in my opinion. I'm actually going to lean towards the hardware side of things. I found these items to be EXTREMELY important when I was building some dual opteron 248's with 8GB ram. 1) First thing you should do is update your bios 2) Use only RAM recommended by the manufacturer. It will probably be considerably more expensive, but NOT doing so can lead to some really weird problems later, resembling bad ram, but you won't be able to track it down in the usual ways with memtest I guess this one isn't hardware, well, it sort of is: 3) Do not run more than 3 or 4GB (I forget) ram with the installation CD's, it'll eventually puke. If you have more ram, add it back later once you have configured a kernel to support it. -- gentoo-user@gentoo.org mailing list
Re: [gentoo-user] Any booby-traps with AMD64?
never tried to use lilo on AMD64, since I switched from lilo to grub and never want to go back. I intend to use the following partition layout... - /8 gigs a little tiny: your /usr gets very big when you have a lot of programs (Gentoo installs everything on /usr by default) and your posrtage cache easily reaches ~3GB...
