* Whole thing running in a VirtualBox VM
Ah, I'm not sure how all this plays with virtualization. VirtualBox looks like a full virtualizer with a separate kernel for the guest, so it probably makes no difference, but if your guest kernel is also your host kernel and it's container-based virtualization, then pid 1 rules may change completely. I'm not familiar enough with virtualized systems or containers to know exactly what happens in that case.
By the way, my Plop Linux boots up such that /proc/sys/kernel/ctrl-alt-del has value 1. Changing it to 0 doesn't enable the three finger salute to run /bin/rc.shutdown reboot.
Well, your host system will definitely catch the 3 finger salute; it won't be sent as is to your guest system. Is there a way for the VM to send an emulated ctrl-alt-del press to the guest ?
If I change it, it reverts to 1 after reboot.
That's just a sysctl in your boot scripts. -- Laurent
