While it's possible to do that, it would need hooks into all filesystems etc. Definitely worth trying once we get some more basic stuff working for ext3 After all the things that need to be saved at the time of taking a checkpoint for any filesystem would be the superblock and inode table (or their equivalents). Everything else is automatically taken care of. -Amit
