Re: [gentoo-user] Some problems while migrating to 64bit
2010/9/15 meino.cra...@gmx.de: thank you for your reply and explanations, Jesus! :) You are welcome. :) The problems are nearly gone in the meanwhile: The HAL-flag was missing for the xorg-sevrer (1.7), after that mouse was recognized and the keyboard was fully functional (with pipes) again. Yes. 1.7 needs USE=hal to be able to use .fdi based configs. Bear in mind what I said in the other mail though: in the future hal will be gone, so save that bookmark for the next time your mouse and keyboard stop working. Fonts: I simply missed to install a couple of fonts. But why they was not in my old world file...dont know. Maybe you installed them manually, that's not uncommon when it comes to fonts. Installing fonts for a given user is a matter of copying them into ~/.fonts/, some desktops like kde might have GUIs to do the same task. -- Jesús Guerrero Botella

Jake Moe Had a similar issue a while ago when I was playing around with this myself. Take a look at the linux boot parameters. The 'theoretical' part is: You need to let the kernel initialize the USB-stick before trying to access it. (This can take some time) There is a delay-option, just can't remember the proper name off-hand. -- Joost I've got USB booting working in a syslinux environment. A delay of 12 seconds is working for me. The syslinux.cfg stanza I use is: LABEL usb KERNEL linux APPEND rootdelay=12 root=/dev/sda2 The usual way for linux on removable usb sticks / disks is to use LABEL or UUID to identify the disks and not the device names, because they will be different in different computers ;) The downside is that you need an initrd to mount the root partition... I think that the usual initrd generated by genkernel works... If you created the rootfs with: mkfs.ext2 -j -LUSBGentoo /dev/sdXY then you can change the kernel parameter to root=LABEL=USBGentoo and your fstab to: LABEL=USBGentoo / ext3 ... You can also use the uuid of the filesystem, find it out with dumpe2fs -h /dev/sdb2 | grep UUID and then use UUID=XXX instead of LABEL=XXX I never really played around with grub and USB booting, so I use syslinux. I create a small FAT partition with syslinux, kernel and initrd image (it gets also pretty handy when you sometimes need to copy something from a windows machine ;) and a second regular ext3 partition for the rootfs. Basically you would do: - partition the stick, mark the FAT partition as bootable/active - format the partitions: - mkfs.vfat -nUSBData /dev/sdX1 - mkfs.ext2 -j -LUSBGentoo /dev/sdX2 - install syslinux (on the FAT partition): - syslinux /dev/sdX1 - mount /dev/sdX2, install gentoo in the usual way - compile the kernel and initrd, make sure required USB stuff is in the kernel (theoretically it could be as modules in initrd... but in-kernel is safer :) if you are in a hurry, or don't know how to create them, get them from a gentoo livecd ;) don't forget to also copy the modules (/lib/modules-XXX/...) from the livecd to the rootfs. - put the kernel and initrd on the FAT partition (I name them vmlinuz.img and initrd.img) - edit syslinux.cfg (on the FAT partition), see http://syslinux.zytor.com/wiki/index.php/SYSLINUX#How_do_I_Configure_SYSLINUX.3F a very simple one from my USB disk: DEFAULT linux LABEL linux SAY Now booting USBGentoo KERNEL vmlinuz.img APPEND root=LABEL=USBGentoo initrd=initrd.img you might also add rootdelay=10 to the options if the usb stick/disk isn't detected quick enough umount, reboot, set the computer to boot from usb, enjoy... ;) Xorg without a config seems to work pretty well on most computers these days, IIRC the alsa modules for soundcards are also autoloaded, so you don't need any fancy hw detection to have a desktop running from USB stick ;) yoyo BTW there is also a manual way

For creating 32bit gentoo on 64bit debian use /usr/bin/linux32 before you chroot to gentoo stage root. So the plan I see is: 1. create gentoo on server (linux32, chroot, compile, emerge -e world, etc). You can always recompile world with another set of CFLAGS if you have different machine, so set CGLAGS for generic 686 2. create experimental environment with debian and compiled gentoo in virtualbox 3. learn about problems (bios, grub, grub2, backup copies) 4. do it :) good luck -- Kacper Kopczyński

However, fstab shows that it's mounted, and /sys/block has entries for the disk, so I'm not sure why it's dropped out. I'm guessing it has something to do with udevd, or uevents? Because shortly before that, I tell it to find the root partition at /dev/sda1, and it starts to boot, but then it loses it. What is that in concrete, it starts? What do you see, hear, smell? Al I'm not sure what you're asking. Can you elaborate as to what you're asking? As I'm in an office, there is no concrete nearby for anything to be in. I see my monitor, I hear my mp3's playing, and I smell my peppermint tea. But I'm pretty sure that's not what you're asking me. :-P If you're asking what, specifically, I mean by it starts, my previous posts show how far into the boot process it gets. If I specify by /dev/sda1, eventually it gets to checking that partition for errors, but fails to find the partition. If I specify by LABEL, then it tells me it can't find the label a bit earlier in the boot process, and asks where it can find the root partition. When I tell it /dev/sda1, it continues to boot, only to stop again at fsck'ing the partition. If I put in the root password for maintenance and have a look, there is no /dev/sda or /dev/sda1 in /dev (nor /dev/hd?, nor /dev/sr?). But a mount command shows /dev/sda1 mounted at /. And /sys/block has sda and under that, sda1. So it's like it sees it, but then it doesn't. Following the sugegstion from YoYo Siska, I've had a look at the various options I can pass to genkernel (I had followed the handbook previously, and hadn't realized there were options I could pass), and am currently rebuilding it with the following command: genkernel --install --slowusb --disklabel all. YoYo pointed out that there was a --disklabel option to pass that'd add disk label support to the kernel, and I noticed the --slowusb option that, from my research, sounds like it may have something to do with my problem. Will let you know after I try that what the results are. Jake Moe
Re: [gentoo-user] Booting Gentoo from USB stick
As I'm in an office, there is no concrete nearby for anything to be in. Lol. Well, there are some other meanings in the latin word concretus. The didn't even have that bleak modern material. We have a different name for it in german and use concretus more in the original sense. If you're asking what, specifically, I mean by it starts, my previous posts show how far into the boot process it gets. If I specify by /dev/sda1, eventually it gets to checking that partition for errors, but fails to find the partition. If I specify by LABEL, then it tells me it I am still asking myself, if it is the USB stick at all that you see starting. Couldn't it be a kernel from the inbuild hard disk? ... wich you would *hear* in that case ... maybe even smell or feel ... Hence I ask you if there linux kernel on the first or second partition of your disk. Al

Hence I ask you if there linux kernel on the first or second partition of your disk. Al Ah, I see. For this test, I have a second PC that I've unplugged the hard drive from. And it's hard drive currently has a work Windows image on it, anyway, so it's definitely not booting from that. :-) I also have finished my new kernel. It now recognizes the root device by label, but still hangs on the fsck. Any more bright ideas? Surely someone has done this already; I can't be the first to try it. Hasn't someone else put a Gentoo install on a USB stick? If I'm correct in my assumptions, it sounds as though GRUB and the kernel are seeing it right, but something in the Gentoo init scripts is breaking it. Can anyone even comment if that assumption is correct? I'm not entirely clear on genkernel and the initramfs it provides, and at what step each of these takes effect. Jake Moe
