RpmXO is a system image scheme in the style of DebXO. It aims to allow the creation and modification of system images for use on the XO with a minimal set of infrastructure.
Downloadable image
I have produce one working Fedora Core 9 image: [] It can be flashed onto a security-disabled laptop using copy-nand. At the OFW prompt with a usb key containing the image and its corresponding crc file inserted:
copy-nand u:\fc9.img
Will install to internal NAND. After completion reboot (with 'bye' or power off).
Tests
My initial tests have used rinse (descendant of rpmstrap) to bootstrap such systems. It should be equally possible to do so using mock. I have also used Fedora core 9 as a system base, but it should be possible to use Fedora 10 in exactly the same pattern.
Setup.
- Bootstrap the system using rinse:
sudo rinse --arch i386 --distribution fedora-core-9 --directory fc9.root
- Install our custom kernel:
wget http://dev.laptop.org/~dilinger/testing/kernel-2.6.25-20080923.3.olpc.f10b654367d7065.i586.rpm sudo rpm -ivh --root fc9.root kernel-2.6.25-20080923.3.olpc.f10b654367d7065.i586.rpm
- Set up files which aren't bootstrapped:
-- /etc/fstab -- /etc/hostname -- /etc/hosts -- /etc/sudoers -- /boot/olpc.fth
- Generate, then modify the initramfs to use busybox to mount the root partition:
sudo linux32 chroot fc9.root mkinitrd /boot/initrd.img-2.6.25-custom 2.6.25-20080925.1.olpc.f10b654367d7065 mkdir fc9.initrd && cd fc9.initrd gunzip -c ../fc9.root/boot/initrd-2.6.25-custom | cpio -i # replace mount command with 'busybox mount' # install busybox rpm cd .. && wget ftp://ftp.isu.edu.tw/pub/Linux/Trustix/releases/trustix-2.2/i586/trustix/rpms/busybox-1.00-2tr.i586.rpm rpm -ivh --root fc9.initrd busybox-1.00-2tr.i586.rpm # then rebuild (as root) sudo -s cd fc9.initrd && find . -print | cpio -H newc -o | gzip -9 >../fc9.root/boot/initrd.img-2.6.25-custom cd .. # and link to the initrd sudo linux32 chroot fc9.root ln -s boot/initrd.img-2.6.25-custom initrd.img
Additional packages I installed:
passwd, sudo, wireless-tools, libertas-usb8388-firmware
When installing packages using yum you must mount proc as follows:
sudo mount -t proc proc fc9.root/proc
Problems I encountered
sudo complains: audit_log_user_command(): Connection refused [1]. This probably is resolved with upgrade to Fedora 10. Testing use of mock now to do so.
