[Lxc-users] Proposal: Change default value of lxc.pivotdir

[Serge Hallyn]

Quoting Jäkel, Guido (G.Jaekel at dnb.de):
> Dear Chris,

Agreed, 'mnt' as a default has no advantage.  The ubuntu template recently
started using lxc_putold.  There's really no reason not to change it in
the source, for everyone.

If this is the case, please Developers, make it a build-in to lxc-start to choose such an arbitrary name based on some adequate prefix (maybe .lxc-pivot is also a good speaking one) AND the actual container name.

This is for containers without their own rootfs I guess?

perhaps just using tempnam suffices.
