v26

• Extra options to commands invoked by mkosi (e.g. when using mkosi boot
  or mkosi shell) should now be delimited from regular options using
  --. Options passed after the verb without using the -- delimiter
  are now interpreted as regular mkosi options.
• Boolean options specified on the command line now always expect a
  boolean argument. For example, --repository-key-check needs to
  become --repository-key-check=yes. The reason for this change is to
  remove ambiguity when parsing e.g. --repository-key-check build
  where build would be interpreted as the argument for
  --repository-key-check whereas now it'll be properly interpreted as
  the verb.
• Teach --verity a new hash value, which skips the verity signature
  partition for extension / portable images. To align the possible values,
  yes is renamed to signed.
• Teach --verity a new defer value, which defers creation of the
  verity signature partition for disk, extension and portable images (but
  still allocates space for it). This is useful to implement offline
  signing of the verity roothash.
• A new way to specify modules included in the initrd has been added.
  The new default is that modules need to be specified to be included.
  Previous separate Include and Exclude options that take regexps are now
  deprecated and are replaced by a single option that takes a list of
  positive and negative globs. The new options are KernelModules=
  and KernelInitrdModules=.
• A new way to specify firmware files included in the initrd has been added.
  Previous separate Include and Exclude options that take regexps are now
  deprecated and are replaced by a single option that takes a list of
  positive and negative globs. The new option is FirmwareFiles=.
• The RuntimeScratch= option has been dropped. Use RuntimeSize=
  instead to grow the image before booting it.
• The CDROM= option has been dropped.
• Unknown settings now generate a warning message instead of failing the
  image build. This allows configs to work across a wider range of mkosi
  versions while still taking advantage of newer settings. MinimumVersion
  can still be used to enforce a minimum version of mkosi that knows all
  required settings.
