Re: Re: USB system with modified kernel and minimal software
Justin, thank you for your comments! I've downloaded: http://live.debian.net/debian-snapshots/live-helper_1.0~a29~20070917.124122_all.deb and http://live.debian.net/debian-snapshots/live-initramfs_1.102.2~20070917.110439_all.deb I did not see any information about downloading lh_helper scripts, so I followed the information at http://www.pendrivelinux.com/2007/05/31/create-your-own-live-linux-cd-or-usb-distribution. This was the reason for my outdated version. No binary image file is created when I try to include the modified kernel. I followed Daniel's suggestions and in an empty directory I did the following: lh_config -d etch -b usb-hdd -p minimal --linux-packages none cp /usr/src/linux-image-2.6.20.19-rt_1_i386.deb config/chroot_local-packages lh_build 21 | tee log In the log file, no error seems to indicate a problem. Does anyone have any suggestion? Best regards, René ___ debian-live-devel mailing list debian-live-devel@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/debian-live-devel

This was the reason for my outdated version. I wouldn't follow this if I were you. It is very out of date. Look at the HOWTOs at http://wiki.debian.org/DebianLive instead. It tends to be kept up to date. For one thing, any config variable prefixed LIVE_ is from an older version of live-helper. All config variables are now prefixed LH_ instead.

When compared with the log of some newer runs (see below), it looks like the squashfs-modules-2.6.18-5-486 and unionfs-modules-2.6.18-5-486 were not included due to --linux-packages none during the lh_config. That's an intentional effect of the none setting. To see why, run vanilla lh_config then read config/chroot (and config/!(chroot) for good measure). New runs: After doing the following in an empty directory, I get a binary.img file. lh_config -d etch -b usb-hdd lh_build 21 | tee log -d sid probably makes much more sense. In particular it will use live-initramfs instead of casper (about this I know nothing more, though). My last run from an empty directory was like this: lh_config -d etch -b usb-hdd cp /usr/src/linux-image-2.6.20.19-rt_1_i386.deb config/chroot_local-packages lh_build 21 | tee log The standard kernel boots ok after I made the above corrections. However the modified kernel stoppes during the booting like this: ... sd 0:0:0:0: Attached scsi removable disk sda loop: loaded (max 8 devices) BusyBox v1.1.3 (Debian 1:1.1.3-4) Built-in shell (ash) Enter 'help' for a list of built-in commands. /bin/sh: can't access tty; job control turned off (initramfs) Does anyone have any suggestion what to do from here? That's due to missing squashfs and unionfs/aufs. You have to compile the modules yourself if you're not using a standard kernel. Note some previous thread messages which document how the kernel image has to be named. In particular, the argument to --linux-flavors must be the same as the make-kpkg option --append-to-version but without the leading hyphen character.

USB system with modified kernel and minimal software

I would appreciate some help. Here is what I'm trying to do: 1. Put a modified kernel with a minimal system on a USB drive. http://lists.alioth.debian.org/pipermail/debian-live-devel/2007-July/001947.html 2. Add two executable programs into /usr/local/bin. 3. Add a service script to start the two programs after the system booted. chroot_local-includes should handle these. Here is what I'm working with: Debian GNU/Linux 4.0r1 Kernel 2.6.20.19 pached with RTAI 3.5-cv Live-helper 1.0~a21-1 Why not the latest? Syslinux 1:3.51-1~e Some of the main problems that I've run into are: 1. After lh_config, change from iso to usp-hdd in config/chroot, lh_build and dd if=binary.img of=/dev/sda, Unknown keyword in syslinux.cfg. shows up 4 times and when I press enter to boot it reports Could not find kernel image: /vmlinuz. I see this too 2. When I try mount -o loop,offset=512 binary.img /mnt, it reports mount: you must specify the filesystem type. Works for me; do you get something like: $ file ./binary.img ./binary.img: x86 boot sector; partition 1: ID=0x6, active, starthead 0, startsector 1, 511999 sectors 4. To reproduce my steps, I use scripts for most of my work. It would be nice to enter something like lh_config -b usb-hdd -p minimal but it just reports lh_config: invalid option - b. I'm going to guess that this goes away if you upgrade.
