The sources.list file may look like (need to check the deb-src entries);

Upgrading Debian 6 kernel

Attempts to do this through apt-get involved upgrading too many packages and in my opinion, was too risky. Therefor, an upgrade from Squeeze to Wheezy was done this way and from there, a kernel [5.15.94] was built on another box, in my case a Debian 11 VM running kernel [5.10.0-21]

Boot from GRUB commandline

There may be occasions where we need to boot manually from the GRUB menu and perhaps realize that you should just have installed LILO in the first place :)

Unable to boot system restored with fsarchiver

 TBA:

GRUB - Embedding is not possible

The following is the output of fdisk -l on both the machine to which the original backups were taken and also a machine to which a successful restoration has been carried out. In the case of the latter, both a physical and a VM.

FEC-A

FEC-B

The df output is the same for both physical machines, as in the device is /dev/cciss/c0d0p* which the VM follows the /dev/sda* format, which perhaps makes sense since the physical machines are the same and both have the same raid controller.

Slackware 15 install on Thinkpad p53

The following is my account of installing Slackware 15 onto a Lenovo ThinkPad P53

Add Java to system PATH variable

 This method seems to work best for me;

There is a script /etc/profile that sets up environment variables and that also includes any scripts in /etc/profile.d so I chose to create a file /etc/profile.d/java.sh with 755 permissions with the following contents;

export JAVA_HOME="/opt/jdk1.8.0_341"
export PATH=$JAVA_HOME/bin:$PATH

Find out which DNS server you're using

 On, we can check /etc/resolv.conf but how do we know which IP is actually being used?
