cryopid: user-space checkpoint and restart

Parent article: Kernel-based checkpoint and restart


There is a user-space checkpoint and restart project
that does not seem to have got much notice.

	http://cryopid.berlios.de/

A quote from its home page about its features:

  - Can run as an ordinary user! (no root privileges needed)
  - Works on both 2.4 and 2.6.
  - Works on x86 and AMD64.
  - Can start & stop a process multiple times
  - Can migrate processes between machines and between
    kernel versions (tested between 2.4 to 2.6 and 2.6 to 2.4).

Ckpt (http://pages.cs.wisc.edu/~zandy/ckpt/) was another user-space solution that worked quite
well for me until glibc & kernel changes bit-rotted it.  Victor Zandy revised it a few times
to keep it alive, but it was originally a PhD research project and he moved on to other
things.  It went down the LD_PRELOAD route that cryopid seems to be avoiding and I suspect
that might have made it more fragile.
