sudo python -m archoffline

--template=<archiso template name>
  Defines which archiso template to adapt into a offline version.
  The default is: releng

--mirrors=<region>
  Uses the current HTTP/HTTPS enabled mirrors from this region.
  Optional magical keywords instead of a region are:
   * copy - copies the /etc/pacman.conf setup to the build env
   * https://... - Will hard-code a specific repo server
   * file:// - Will use a locally stored mirror as the build env repo

--packages="<list of packages>"
  A space separated list of packages to ship with the iso
  aside from the default packages in archiso packages.x86_64

--skip-validation
  Skips validation of packages and AUR packages. Improves build speed.

--rebuild
  Cleans and re-creates the builddir and other dependencies

--breakpoint
  Creates a breakpoint right before mkarchiso is executed.
  This way you can do manual changes to the ISO layout before
  mkarchiso is executed.

--repo=<repo name>
  You can override the repository name created inside the ISO.
  The default is: localrepo

--builddir=<path to folder>
  You can override the build directory for the ISO.
  The default is: ./archiso_offline/

--verbose
  Enables printout for all the syscalls that are being made.
  (For instance output from mkarchiso)

--archinstall
  Clones in archinstall to /root/archinstall-git with the given --ai-branch and
  --ai-url.
  (This is optional, archinstall stable is shipped as a package already)

--ai-branch=<archinstall branch to clone>
  This can override the default `master` branch.

--ai-url=https://github.com/archlinux/archinstall.git

--aur-packages="<list of AUR packages>"
  A space separated list of AUR packages that will be built and
  shipped within the ISO mirror as a standard package.

--aur-user=username
  Set a build-user username, if this user does not exist it will be
  created. If the user does not have an entry in /etc/sudoers an entry
  will be created with NOPASSWD only if the user is locked on the local system.
  (the AUR user will be deleted as well as the /etc/sudoers entry unless pre-configured)

--resources="list of assets/resource URL's"
  A semi-colon (;) separated list of resources to package into the ISO.
  The resources will be stored in /root/resources. Acceptable URL's examples:
  https://
  /local/path.txt
  git://
  https://.git  (note: trailing .git important to trigger git clone)

--customize=<path to script>
  Add a script that will be run from within Archiso and executed before
  the ISO is finalized.

--autorun="<commands to autorun on every boot>"
  This injects a .zprofile auto-run string, be mindful of quotation issues:
  Injects: [[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && sh -c "{string}"

--save-offline-repository-cache
  Saves the offline repository cache (packages) in the ISO between rebuilds.
  It's done by moving out the `--repo` folder/cache out and in the --builddir.

--silent
  Does not prompt for anything, will skip by default or error out if key parameters
  were not found during execution.
