+# Making a new Google Compute Engine image
+#   * Create a raw disk 4GiB image dd if=/dev/zero of=disk.raw bs=1M count=4096
+#   * Boot VM (qemu-system-x86_64 -cdrom (haiku-release.iso) -hda disk.raw -boot d --enable-kvm -m 4G
+#     * Partition new disk
+#       * 32 MiB EFI System Data. FAT32 named "ESP"
+#       * Rest of disk, Haiku, BFS, named "Haiku"
+#     * Install Haiku to it new disk
+#     * Allow installer to Reboot, *boot again from CD*
+#     * Setup EFI bootloader
+#       * mount "haiku esp", mount "ESP"
+#       * Copy all contents of "haiku esp" to "ESP"
+#       * unmount "haiku esp", unmount "ESP"
+#     * Mount new Haiku install.  (should mount to /Haiku1)
+#     * Run this script (sysprep-gce.sh /Haiku1)
+#     * Manually copy over latest r1beta4 haiku, haiku_devel, haiku_data_translations, haiku_loader
+#       * Needed on r1b4 due to / permissions fix needed by sshd
+#     * Shutdown VM.  DO NOT BOOT FROM NEW DISK!
+#       * Booting from new disk will cause SSH host keys to generate! (#18186)
+#   * Compress tar cvzf haiku-r1beta4-v20221222.tar.gz disk.raw
+#   * Upload to google cloud storage bucket for haiku.inc (ex: haiku-images/r1beta4/xxx)
+#   * Import image
+#     * compute engine -> images
+#     * create image
+#     * source: Cloud storage file -> haiku-images/r1beta4/xxx
+#     * name: haiku-r1beta4-x64-v20221222
