How to make a custom ISO image: Difference between revisions

Revision as of 18:43, 9 May 2020

One way to completely re-build custom images is to use a script like alpine-make-vm-image.

If you want to make a customized installer, you need to create .default_boot_services which will cause mkinitfs to create the defaults for the live image.

An alternative

It's possible to commit and load ISO image customizations to and from disk.

-Once you have booted and customized the system that was booted from an ISO, you can now configure the ISO to load the customizations as follows:
+* If you want to make a customized installer, you need to create <code>.default_boot_services</code> which will cause <code>mkinitfs</code> to create the defaults for the live image.
-* Generate an APKOVL file with [[Alpine_local_backup|lbu]], <code>lbu ci</code>
+== An alternative ==
-* The Alpine ISO looks for an APKOVL Volume in mountpoints below /media/, or can be pointed to a web server.
-* If you put the APKOVL file on a webserver, you need to add a customized url with the <code>APKOVL</code> boot parameter.

-Notes:
-* Any packages you add to /etc/apk/world of your lbu will automatically be installed onto the live system image.
-* If you don't have a web server you can run busybox's httpd temporarily - <code>busybox httpd -p 127.0.0.1:80</code>
-* In general, <code>lbu</code> will only handle files in <code>/etc</code>, to customize this further, you need to add additional files.
