> Hello,

> I am trying to get criu to do something on an "armv7l GNU/Linux"
> platform. I am running a 4.4.8 kernel. I think I successfully selected
> the options you mention in https://criu.org/Installation .
>
> This is what I get when I run the first checks:
>
> root at POWERScope:~ criu check
> Looks good.
> root at POWERScope:~ criu check --extra
> Warn (criu/cr-check.c:705): Dirty tracking is OFF. Memory snapshot will not work.
> Error (criu/tun.c:61): Can't check tun support: No such file or directory
> Error (criu/cr-check.c:919): cgroupns not supported. This is not fatal.
> Error (criu/cr-check.c:1021): The TCP_REPAIR_WINDOW option isn't supported.
> Error (criu/cr-check.c:965): TCP_REPAIR can't be enabled for half-closed sockets
> Error (criu/cr-check.c:1035): No userns proc file: No such file or directory
> Warn (criu/cr-check.c:1054): Loginuid restore is OFF.
> Looks good but some kernel features are missing
> which, depending on your process tree, may cause
> dump or restore failure.
>
> Do I need to get worried by this?
>
> It seems I do, because when I run the example on
> https://criu.org/Simple_loop with setsid, even just dumping this simple
> program fails:
>
> root at POWERScope:~ setsid ./test.sh < /dev/null &> test.log &
> root at POWERScope:~ ps -C test.sh
> PID TTY TIME CMD
> 746 ? 00:00:00 test.sh
