[gentoo-user] Make Gentoo Live USB Stick
Hello, This question more than likely has been posted before, either to this or some other list. If so, then please let me know and I'll start searching. I want to make a Gentoo Live bootable USB stick using the available Gentoo Live DVD iso. Can this be done by simply copying the iso file to the USB drive with a utility like dd? Or are there some special files that need to be copied to the boot sector? Unetbootin (unetbootin.sf.net) is a GUI program that claims to do this, but there must be a simpler CLI alternative.

For example, after following the procedure one comes to the point: "Download the Gentoo Weekly Minimal Install CD for your architecture from your local Gentoo Linux mirror ..." Huh? What happened to the Live DVD iso stuff? It's not mentioned. I ended up using Unetbootin from an MS Windows machine to copy the Gentoo Live DVD iso to a USB thumb drive. I'm just wondering if there is a CLI procedure to copy same from Linux. Frank Peters

I use lilo on all of my LInux machines, and when the time comes to switch to EFI, I will switch to elilo. In fact, the Intel MB's that I use all have the capability to use EFI and I will shortly be experimenting with EFI/elilo. My needs are simple and simple tools are appropriate and available. Wouldn't it be a shame if, by popular assent, nothing else were maintained other than grub. Frank Peters
[gentoo-user] Kernel-3.4.4 No USB Keyboard
Is anyone having problems with the latest kernel-3.4.4? After configuring with the same .config file that I used for 3.4.0, the new 3.4.4 kernel boots but it cannot read the USB keyboard. Presumably the USB mouse is also affected. Here are, I believe, the relevant lines from the kernel log for the working 3.4.0: usb 1-1: new high-speed USB device number 2 using ehci_hcd hub 1-1:1.0: USB hub found hub 1-1:1.0: 6 ports detected usb 1-1.1: new low-speed USB device number 3 using ehci_hcd input: Microsoft Natural Keyboard Elite as /devices/pci:00/:00:1a.0/usb1/1-1/1-1.1/1-1.1:1.0/input/input0 generic-usb 0003:045E:000B.0001: input: USB HID v1.10 Keyboard [Microsoft Natural Keyboard Elite] on usb-:00:1a.0-1.1/input0 usb 1-1.3: new low-speed USB device number 4 using ehci_hcd For comparison, the corresponding lines from the 3.4.4 log are: usb 1-1: new high-speed USB device number 2 using ehci_hcd usb 1-1: device descriptor read/64, error -110 usb 1-1: device descriptor read/64, error -110 usb 1-1: new high-speed USB device number 3 using ehci_hcd usb 1-1: device descriptor read/64, error -110 usb 1-1: device descriptor read/64, error -110 usb 1-1: new high-speed USB device number 4 using ehci_hcd usb 1-1: device not accepting address 4, error -110 usb 1-1: new high-speed USB device number 5 using ehci_hcd usb 1-1: device not accepting address 5, error -110 As I mentioned, the configuration has not changed since 3.4.0. Unless I am missing some new parameter somewhere the kernel-3.4.4 must be broken. The only related report that I could find is here: http://bbs.archlinux.org/viewtopic.php?pid=1122440 Can anyone confirm or refute this? Frank Peters

In the "General setup" options for kernel .config file, there is an option called "Configure standard kernel features (expert users)." There is also an associated admonition: "Only use this if you really know what you are doing." Since the help descriptions for these options are fairly easy to understand I decided to manually set some of these options. For reasons that I can't understand this caused the USB problems. Setting this option to "No" fixed everything and now the kernel-3.4.4 works nicely. It would be beneficial if anyone who truly is an "expert" could comment on how setting these options could wreck the USB system. Frank Peters

The problem arose because I manually set some "expert only" parameters during the kernel configuration. For reasons that I can't explain, this messed up the USB system. Frank Peters

However, I have read in several places that any potential problem on Linux systems had been traced to a bug that was fixed several kernel releases ago. Anyone who keeps up to date should have experienced nothing. Frank Peters

A released kernel should always compile. The error possibly refers to missing #include statements or even an incorrect compiler option. On LKML, a failure of the kernel to compile will usually get immediate attention. Frank Peters
[gentoo-user] Linux and the Higgs
Linux was used to find the Higgs: http://www.reddit.com/r/linux/comments/w2ly6/new_boson_found_by_linux/ I am not really surprised, but what does disturb me is that the distros used in the effort were mainly "Scientific Linux and Ubuntu." Where was Gentoo? Somebody had better counsel these scientists to be better able to discern the quality of a Linux distro. Frank Peters

AFAIK, Gentoo does not have a script or an option to back up the world file and other associated files. After I finish even a small update, I will run my own script to copy /var/lib/portage and /var/db/pkg to another drive for safekeeping. There may not be much point in doing so. If my main HDD fails I will have to reinstall the entire OS, but just in case of some freak accident that may affect the world file I will make the backup. My whole system I will backup once a week, and all very important new data will be backed up (almost) immediately. Frank Peters
