I have started by creating an etch installation in /target
# debootstrap etch /target
afterwards, I chroot into the new installation and change some stuff:
# mount --bind /dev /target/dev # chroot /target # dpkg-reconfigure -a # cat >/etc/fstab /dev/sda1 / ext2 ro 0 0 tmpfs /tmp tmpfs nosuid,nodev,noexec 0 0 ^D # rmdir /var/tmp # ln -s /tmp /var/tmp # sed -i -e 's/RAMRUN=no/RAMRUN=yes/' /etc/default/rcS # sed -i -e 's/RAMLOCK=no/RAMLOCK=yes/' etc/default/rcS # rm /etc/mtab # ln -s /proc/mounts /etc/mtab # touch /fastboot # echo asaph >/etc/hostname # echo '127.0.0.1 localhost asaph' >/etc/hosts # aptitude update # aptitude purge sysklogd klogd logrotate cron # aptitude install less # aptitude install lilo
I have a custom-built low-latency kernel on that system. That kernel is in /target/linux-image-2.6.24.7-rt21-asaph_custom.1_i386.deb
# cat >/etc/lilo.conf
boot=/dev/sda
root=/dev/sda1
map=/boot/map
prompt
timeout=20
image=/vmlinuz
label=Linux
read-only
initrd=/initrd.img
image=/vmlinuz.old
label=LinuxOLD

optional
initrd=/initrd.img.old
^D
# mount -t proc proc /proc
# dpkg -i /linux-image-2.6.24.7-rt21-asaph_custom.1_i386.deb
# aptitude install linux-image-2.6.24.7-rt21-asaph
# cat >/etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 10.193.1.17

gateway 10.193.1.1
^D
# echo 'nameserver 10.193.1.1' >/etc/resolv.conf
# aptitude install openssh-server
# ^D
I'm now back out of the chroot. I need to re-run lilo on both systems since the package installation has overwritten the boot loader on /dev/sda (which is a temporary disk which will be removed when the system is ready):
# lilo # chroot /target lilo -b /dev/sdb # halt
Now move the new hard-drive to /dev/sda and restart the system. The system should now be reachable on 10.193.1.7 via ssh.
Since I use this system as an audio appliance, here the further configuration steps
I installed the following packages:
alsa-tools alsa-tools-gui alsa-utils ntpdate qjackctl sooperlooper meterbridge alsaplayer-jack jack-rack stow timemachine sndfile-programs python-ecasound ecasound xbase-clients psmisc xterm nfs-client
In /etc/security/limits.conf, I setup the following to allow realtime access to the audio group:
* hard rtprio 0 * soft rtprio 0 asaph hard rtprio 80 asaph soft rtprio 70
Additionally, I had to adjust /etc/pam.d/su and uncomment the pam_limits.so line.
