ISO remastering

There are scripts to re-build completely custom images, like

alpine-make-vm-image

and the original

mkimg.

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 a writable storage.

Booting an ISO image with local customizations

From a dedicated boot media, obviously.

-* Generate an APKOVL file with [[Alpine_local_backup|lbu]], <code>lbu ci</code>
-* Alpine ISO requires the OVL Volume to be hosted on a web server. Put the APKOVL file on a webserver and identify the url.
-* Uncomment the <code>APKOVL</code> line in the alpine flavor of your choice and set it to the address of your ovl volume.
-Notes:
+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.
-* 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.
