How to reconstruct Parted Magic ISO through adding packages from Slackware

Estimated Reading Time: 5 minutes

Parted Magic is a complete hard disk management solution.Parted Magic is a small live CD/USB/PXE with its elemental purpose being to partition hard drives. As per the definition on partedmagic.com,

“PartedMagic has the tools to get the job done. With the Partition Editor you can re-size, copy, and move partitions. You can grow or shrink your C: drive. Create space for new operating systems. Attempt data rescue from lost partitions.”

Recently I dirtied my hands on reconstructing Parted Magic ISO through adding packages from Slackware. Here is how I achieved it –

Step-1:

Starting with Parted Magic 5.9 the mkgriso script is provided in the root of the iso. It is recommended to follow the instructions in there and to use that script to recreate the iso.

Follow the below steps:

#mkdir /mnt/cdrom
#mount -o loop pmagic-x.x.iso /mnt/cdrom
#cp -a /mnt/cdrom .
#umount /mnt/cdrom

Step-2: Adding Slackware Packages:

Parted Magic is not Slackware based, but the main tool chain was compiled on Slackware. If you would like to add programs your best bet is to use TXZ packages from Slackware 13.x.

If you would like to add programs, put the txz files in cdrom/pmagic/pmodules directory.Parted Magic will install any packages it finds in the /pmagic/pmodules directory.

The most comprehensive place for Slackware packages is slackbuilds.org. You download the source and a build file which you use to compile the program and make the package. Slackware packages are basically just ordinary compressed tar files.

Let’s download an example build, say apache-maven

ls

[root@localhost pmodules]#

#pwd
/mnt/isoss/pmagic/pmodules
[root@localhost pmodules]# ls
PMAGIC_2015_01_13.SQFS  scripts
[root@localhost pmodules]#

So, now we have the following source and builds downloaded

[root@localhost pmodules]# ls
apache-maven-3.1.1-bin.tar.gz  PMAGIC_2015_01_13.SQFS
apache-maven.tar.gz            scripts

Step-3: Remastering the ISO

Now as I have added these sources(packages) into pmodules directory.
Its time to run mkgriso script:

cp -rf mkgriso pmagic-custom/
cp: overwrite ‘pmagic-custom/mkgriso’? y
[root@localhost opt]# ls
GPL  mkgriso  pmagic-custom
[root@localhost opt]# cd pmagic-custom/
[root@localhost pmagic-custom]# ls
boot  EFI  GPL  mkgriso  pmagic  rh
[root@localhost pmagic-custom]# chmod +x mkgriso
[root@localhost pmagic-custom]# ./mkgriso

>>> /opt/pmagic_2015_01_13T.iso created
[root@localhost pmagic-custom]# ls
boot  EFI  GPL  mkgriso  pmagic  rh
[root@localhost pmagic-custom]# cd ..
[root@localhost opt]# ls
GPL  mkgriso  pmagic_2015_01_13T.iso  pmagic-custom

Hence the pmagic_2015_01_13T.iso is created.

Just mount the ISO and you will see the particular packages and module is loaded. If the module is bind to kernel, you might need to compile the kernel.

Hope it helps !!!
