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 This was the reason for my outdated version.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This was the reason for my outdated version.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 It is very out of date.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.

Bug#442922: live-helper: d-l overwrites its own files due to symlinks
Package: live-helper Version: 1.0~a27-1 File: /usr/share/live-helper/data/debian-cd/ On an amd64 machine which had the following upgrade path: .../dpkg.log.1:2007-08-31 install live-helper none 1.0~a24-1 .../dpkg.log:2007-09-04 upgrade live-helper 1.0~a24-1 1.0~a25-1 .../dpkg.log:2007-09-06 upgrade live-helper 1.0~a25-1 1.0~a26-1 .../dpkg.log:2007-09-10 upgrade live-helper 1.0~a26-1 1.0~a27-1 debsums gives the following: /usr/share/live-helper/data/debian-cd/etch/i386_udeb_include FAILED /usr/share/live-helper/data/debian-cd/etch/exclude-udebs FAILED /usr/share/live-helper/data/debian-cd/etch/i386_netinst_udeb_include FAILED /usr/share/live-helper/data/debian-cd/etch/i386_businesscard_udeb_include FAILED /usr/share/live-helper/data/debian-cd/etch/powerpc_udeb_include FAILED Likely due to the following wrongness: drwxr-xr-x 2 root root 4096 2007-09-10 05:07 etch lrwxrwxrwx 1 root root4 2007-09-04 10:28 lenny - etch lrwxrwxrwx 1 root root5 2007-09-10 05:07 sid - lenny I think the rule is: dpkg will not replace a directory with a symlink or a symlink with a directory. So it's necessary when converting a pathname between the two types to rm it in preinst, probably conditionally on its existence, the version, and its target (and perhaps the existence thereof). Ideal is inverse support in postrm abort-upgrade to undo that change. ___ debian-live-devel mailing list debian-live-devel@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/debian-live-devel

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.

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.

That certainly sounds like a good plan for a small number of computers, thanks. I'm running a whole lab with of a bunch of identical CDs, and 15*$30 = $450, which is more than I care to spend at the moment. To everyone, I have successfully created a 686 flavoured GD, which is now working beautifully. Thanks for all your suggestions. It might be a good idea to make a bit clearer on the wiki what is the implication of the 486 default flavour for use on modern machines - I imagine I'm not the only one it's surprised. Is the wiki for anyone to edit? If so, I can happily do this myself. To solve the problem of files I needed often (but might want to change from time to time) I made sure the CD included ssh, then just scp in a launcher script from a server machine, and use that launcher script to pull in everything else I need. Saving output files is also done by scp. Thanks to developers of live-helper - it's a great tool.
