Virtualised Debian Squeeze on Readynas

After burning my Readynas through reckless upgrades I noticed some comments referencing chroot. This promised a way to have an up to date system and protection from rogue packaging problems.

Installing new Debian systems with debootstrap

root@velvet:/# cat /etc/debian_version
4.0

apt-get install debootstrap

cd /usr/share/debootstrap/scripts
ln -s lenny squeeze
debootstrap squeeze /c/home/squeeze

chroot /c/home/squeeze



root@velvet:/# cat /etc/debian_version
6.0.4

All very simple and very nice.

Trying to install Alien on my Readynas Pro 2, which runs the ancient Debian etch release, corrupted the os and needed a rebuild of my environment. This entry documents the recovery steps.

Java

Java install seems to have got a lot more complicated since the initial install a year or so back. I could not find an apt package. So manual download from:

http://www.java.com/en/download/linux_manual.jsp?locale=en

Linux (self-extracting file) filesize: 32.8 MB

to /opt/java/jre1.7.0_04, then try to patch up a bit...

update-alternatives --install "/usr/bin/java" "java" "/opt/java/jre1.7.0_04/bin/java" 1 
update-alternatives --set java /opt/java/jre1.7.0_04/bin/java

(Some related stuff, did not use options or more)

BaseX

The BaseX package required a forced install, due to the broken java..

Installed tagsoup from the deb file

Updated my init.d script (based on the Redis one). And invoke at boot, see
