linux/seccomp.h may not be available, and the seccomp mode might not be
listed in /proc/pid/status, so let's not assume those two things are
present.
v2: add a seccomp.h with all the constants we use from linux/seccomp.h
v3: don't do a compile time check for PTRACE_O_SUSPEND_SECCOMP, just let
ptrace return EINVAL for it; also add a checkskip to skip the
seccomp_strict test if PTRACE_O_SUSPEND_SECCOMP or linux/seccomp.h
aren't present.
v4: use criu check --feature instead of checkskip to check whether the
kernel supports seccomp_suspend

CRIU (Checkpoint and Restore in Userspace)
An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.
The project home is at http://criu.org.
Pages worth starting with are:
- Kernel configuration, compilation, etc
- A simple example of usage
- More sophisticated example with graphical app
