"""
Run configuration operations during system boot.

Some uaclient operations cannot be fully completed by running a single
command. For example, when upgrading uaclient from trusty to xenial,
we may have a livepatch change in the contract, allowing livepatch to be
enabled on xenial. However, during the upgrade we cannot install livepatch on
the system because the running kernel version will not be updated until reboot.

Pro client touches a flag file
/var/lib/ubuntu-advantage/marker-reboot-cmds-required to indicate this script
should run at next boot to process any pending/unresovled config operations.
