mksandbox-1.2:
* Mount /proc read-write on Linux, it appears to be required for e.g.
groupadd to function correctly.
* Add new --rodirs and --rwdirs options, which allow arbitrary lists
of directories to be mounted appropriately inside the chroot.
* Add --without-pkgsrc which prevents the default pkgsrc directories
from being mounted.
This allows mksandbox to be easily used for chrooted pbulk setups, using
a simple invocation such as:
mksandbox --without-pkgsrc --rodirs=/usr/pbulk --rwdirs=/shared /chroot
