[Debian] Re: Bug#438798: Deinstalling vzctl in VE crashes VE

[Kir Kolyshkin]

Joachim,

I see two problems here -- first is vzctl not detecting it is running
inside a VE, and second is "crash". First problem is clear, we will fix
it in vzctl.

As for the second one -- can you please be more specific and describe
what does "crash" means? Is that the deinstallation process that fails
to deinstal vzctl? Or is that your VE that was like shot down? Or
something else?
