Problem is that when I got this severer at my ISP I used their default image for RHEL 6 which only allocates 100MB for /boot clearly this is not enough. How can I get around this problem, is it safe to delete any of the above files some of them seem to be on the disk more than once? Is there some way of expand /boot without re-imaging the machine?
