   overrides while adding the ability to override GIT_BASE.

xenapi: /boot/guest should point to local SR

Fixes bug 1037516

This patch creates a directory os-guest-kernels inside the local SR, and
sets up /boot/guest to be a symlink to that directory. This way
OpenStack won't pollute Dom0's filesystem.

Add err()/err_if_not_set()

Linux Mint support

This patch allows DevStack installation on Linux Mint. Installations
on Linux Mint previously failed since its distribution ID did not
match any of the package installation methods and defaulted to using
rpm packages. Linux Mint is a Ubuntu derivative and such does not have
native support for rpm packages.

This change adds "LinuxMint" to the distribution matching options along
with Debian and Ubuntu.
