From 2014844107fc356e945fb637ef9179bc29656864 Mon Sep 17 00:00:00 2001

Subject: [PATCH] customize: rebase to the common/mlcustomize/Guest_packages
interface
Replace the "guest_install_command", "guest_update_command" and
"guest_uninstall_command" helper functions with the corresponding
functions from libguestfs-common, interface mlcustomize/Guest_packages.
Add a wrapper function for (a) dealing with the exceptions uniformly
(keeping the original behavior of virt-customize), (b) centralizing the
[g#inspect_get_package_management root] call. Regarding (b), the wrapper
function fills in the last argument [package_management] of the
Guest_packages functions; thus, pass partially applied functions to the
wrapper at the original call sites.
