4 ways to boot Porteus.

Post#1 by Ed_P » 29 Nov 2021, 18:41

There are 4 Boot Options that I use.

1. Always Fresh: Nothing but the ISO files that were downloaded.

2. Always Fresh + (plus): The ISO files that were downloaded plus downloaded modules I like to use. NO changes.

3. Always Fresh ' (prime): The ISO files that were downloaded plus downloaded modules plus frozen changes I've made.

4. Live with changes: The ISO files that were downloaded plus downloaded modules plus changes I've made and changes I want to keep.

Options 1, 2 and 3 are useful in debugging problems, determining where the problem lies, and thus determining where the resolution needs to be made. I primarily boot the #3 option, it has my changes and prevents unexpected changes from impacting my system.

I boot the Porteus ISOs directly, via grub2 and to save changes I use 2 options:

1. A Porteus SaveFile .dat file plus the changes=EXIT cheatcode.

2. A script to create a module of the changes I've made and want to keep.

With the #1 option I try to keep my changes to small files and thus have a savedat file of 512MB or less. Larger changes like videos, pictures, and downloads I save on drives outside my booted system and thus outside my save.dat file.

With option #2 I determine what changes a new app makes by running the changes-time command. I wait a few minutes after I've activated the new app then use the app adding options I like to it, I then run the changes-time command, in terminal, to see what files and folders got updated. I then add the changed files/folders to the script I use to save my changes.

For newbies who may not be use to creating scripts and making modules there is a shortcut that can be used to boot to option #3 with saved changes. Make a copy the save.dat file with an extension of .xzm and boot with it as a module and without the changes= cheatcode. cp /changes/save.dat /modules/save.dat.xzm

I hope this helps. :)
