I compared Moblin 2.1 and Chrome OS before time.
Project page Moblin 2.1: http://moblin.org Chrome OS : http://www.chromium.org/chromium-os
Kernel Moblin 2.1: 2.6.31(-netbook, -ivi, -menlow, -mrst) Chrome OS : 2.6.31(-chromeos-intel-menlow) but It isn’t included psb driver Currently, I think this kernel is for netbooks, CULV laptops
Base distribution Moblin 2.1: Original Chrome OS : Ubuntu Karmic
Kernel parametor Moblin 2.1: vga=current quiet root=/dev/sdx (no initrd) Chrome OS : (USB) quiet console=tty2 initrd=initrd.img init/sbin/init boot-local rootwait root=LABEL=C-ROOT ro noresume noswap i915.modeset=1 loglevel=1 (HDD) quiet console=tty2 init/sbin/init boot-local rootwait root=/dev/sda ro noresume noswap i915.modeset=1 loglevel=1
Both of them uses ply-image for boot splash.
Boot loader Moblin 2.1: GRUB1 Chrome OS : extlinux
Fast boot Mobln 2.1: ~10sec Chrome OS: ~5, 6sec? Anyway USB boot is faster than Moblin. this was as fast as HDD boot. And Boot Booster for EeePC is enabled by second partition of EFI.

Some applications Moblin 2.1: connman 0.45, clutter 1.0.8 Chrome OS : connman 0.42, clutter 0.9
Maybe there are Chrome OS packages in the following. chronos@localhost:~$ dpkg -l | grep chrome ii chromeos-acpi 0.1 chromeos acpi scripts ii chromeos-assets 0.3 Chrome OS platform assets ii chromeos-chrome 0.1 chromeos chrome ii chromeos-connman 0.3 connman ii chromeos-cryptohome 0.1 Helper scripts which smooth the integration ii chromeos-init 0.3 Chrome OS init scripts ii chromeos-installer 0.1 Chrome OS installer ii chromeos-libcros 0.1 Chrome OS plug-in library for Chrome ii chromeos-login 0.4 Chrome OS login manager ii chromeos-monitor-reconfig 0.1 Small module that will reconfigure an extern ii chromeos-pam-google 0.10 Linux-PAM module to authenticate against Goo ii chromeos-ply-image 0.1 Chrome OS boot splash image loader. ii chromeos-screenlocker 1.0-1 Screen locker configuration for Chrome OS. ii chromeos-wm 0.4 Chrome OS window manager ii chromeos-wpasupplicant 0.1 wpasupplicant ii e4fsprogs-git 1.41.9-1chromeos1 statically-linked version of the ext2/ext3/e ii linux-image-2.6.31.4-chromeos-intel-menlow 002 Linux kernel binary image for version 2.6.31 ii slim 1.3.1-chromeos3 desktop-independent graphical login manager ii xscreensaver 5.0.8-chromeos2 Screen locker for Chrome OS ii xserver-xorg-video-openchrome 1:0.2.903+svn758-0ubuntu1 X.Org X server – VIA display driver
Installer Moblin 2.1: moblin-installer(anaconda) Chrome OS : chromeos-installer(installation script) this script deletes all partition. so It’s no flexibility.
Misc Chrome OS is splitted 3 partitions. one is data cache partition, two is EFI partition for Boot Booster. three is rootfs parition. /home to tmpfs to mount as. I think that is for appliance more than Moblin. As you know, Moblin is supported Atom processor based Netbooks, Entry-level PCs, MIDs, and In-Vehicle Infortainments. Long time ago, I suggested moblin should define security. e.g SELinux, AppArmor and son. But currently, Moblin is no defined. I think It’s no good. :-(
