ISO remastering

There are third party scripts to re-build completely custom images, like alpine-make-vm-image (works to only make a disk based VM image) and there is Alpine's original mkimg. (creates a diskless ISO file - usually what you want for QEMU and Proxmox)

An alternative

It's also possible to commit and load ISO image customizations to and from a writable partition when booting in Diskless Mode.

-Once you have customized your custom ISO, you can now setup the live environment to operate outside of the standard installer as follows:

-* Generate an APKOVL file with [[Alpine_local_backup|lbu]], <code>lbu ci</code>
+== An alternative ==
-* 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:
+It's also possible to commit and load ISO image customizations to and from a writable partition when booting in [[Installation#Diskless_Mode|Diskless Mode]].
-* 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.
-* 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.

-[[Qemu#Live_mode| Qemu]] is useful for a quick test of your created ISO image.
