Hi,

yes : in the vcontext.c code, there is :
- mkdir (and if it fail, exit)
- mount (and if it fail, exit)
- pivot_root (and if it fail, exit)
- umount (and if it fail, exit)
- rmdir (and if it fail, exit)
so ... If I pre-create the .oldroot folder, I still have to patch the code for this to work, and remove both the mkdir and the rmdir
Since I wanted to make it works for everybody, not only the one using read-only root,
I proposed this patch which is far better since /var/run is bound to be read-write anyway.
