Update script or GUI

[rych]

With the welcome frequent releases of PorteuX, how would one automate the (self-)updating process with a script? It would extract the base module folder from the latest PorteuX iso of the correct channel and for the right desktop, also the new vmlinuz/initrd pair, and update the optional modules (if present) e.g. 05-devel, 08-nvidia, etc. ... and delete the old versions. The latter suggests that this script would run from a different system, in my case Porteus. I know Porteus has figured out how to update itself by scheduling the deletion of old files at the next reboot, but that's too difficult/risky to implement I guess.

If nobody has such a script yet, I'm going to have to write it myself

You're welcome to tweak this old Porteus script that I use to fit your needs.

With the welcome frequent releases of PorteuX, how would one automate the (self-)updating process with a script?

This script below does not answer your question, directly:

• Code: Select all

  https://github.com/robang74/porteus-usb-installer

but a possible approach when a major version release update is required can be:

1 keep your persistence (the original USB untouched)

2. re-creating a new LIVE system (with the same modules)

3. copy your persistence on the new storage support.

Clearly, the #2 would be much easier if a recipe of your current system would be available:

• viewtopic.php?p=102683#p102683

as described here.

I have a script now, update_porteux published here: Self-updating PorteuX

[Ed_P]

Yup. Amazing what a 15 line script can do when you know what you're doing. porteux is one of the best.
