I already tried mounting the tmpfs before starting the vserver, hence
why I thought it was weird.
The thing is, /vservers/.pkg doesn't exist in the vserver namespace -
the package management is external to the vserver, so I cannot put it in
the internal vserver namespace. Or am I wrong here? Is the
/vservers/.pkg available inside the vserver context?
The only other thing that comes to mind is internalizing the package
management to the vserver, and have tmpfs mounted inside it, but that's
a bit of a bodge, especially as I would like to keep the vserver package
management external.
