Good to know, but I'd like to stick with 2.6.32 if possible. >> But now I see that signal forwarding was just added to lxc-init, would >> you consider something like that in lxc-start as well? > > It's the lxc-init process who forward the signals.

Sure, but it isn't me who sends the signals, but that who spawned lxc-start. I'd like to use lxc-start a wrapper, invisible to the parent and the (jailed) child. Of course I could hack around this by not exec-ing lxc-start but keeping the shell around, trap all signals and lxc-kill them forward. But it's kind of ugly in my opinion. -- Thanks, Feri. ------------------------------------------------------------------------------ _______________________________________________ Lxc-users mailing list Lxc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/lxc-users
