    Change a user’s UID 

    First login as root – Clean login – sudo will not work if you’re changing a UID on an already logged in user.

    Find the user’s old UID:

    uid=1000(user1) ….

    Change the UID:

    Update files and directories owned by the user to the new UID:

    Reboot and the UID has been changed.

    Fixing eth numbering 

    While moving virtual machines around, it will usually mean a change on MAC addresses on the networking interfaces, which will create new eth nodes on the machine.
    Reasons for the renaming of eth nodes on the machine, is due to the persistent mapping on Linux systems using udev.
    Fixing this is done by removing the entities in the /etc/udev/rules.d/70-persistent-net.rules and reboot the machine.
