-## usage: fx boot [--netboot] [--force-pave]
-##                [--artifacts <dir>]
-##                [--sign-tool <path_to_sign_tool>]
-##                [--bootloader <path_to_prebuilt_bootloader>]
-##                [<type>] -- [bootserver arguments]
-##   <type>        see "--help" for list (default: x64 for x64 / arm64 for arm64)
-##   --netboot     Boot from ramdisk containing FVM
-##   --force-pave  Force the target device to pave to persistent storage
-##   --sign-tool   Optional executable to sign kernel images.
-##   --bootloader  Flash the bootloader in addition to other partitions. Only
-##                 works with a limited number of device types.
-##
-## If <type> is omitted, a guess is made based on $FUCHSIA_ARCH. For x64, all
-## x64 images will be supplied (resulting in an FVM pave). For arm64 the default
-## <type> is netboot.
