During an install, the partition that is going to become /
would be mounted on /mnt/sysimage and
that which will be /usr would be on /mnt/sysimage/usr.

You shouldn't actually have to do an anaconda install to get from
SL54. to sl5.5, a yum upgrade should work.
But yes you ran out of disk space on /usr, which is by far where
most of the distribution lives.

How big is your / partition?  Is it enough to contain all that it contains
now plus all the 8GB of /usr plus the extra stuff you still have to put 
in?

do you have any other partition that has 2G or more free?

If so, you could boot in single user mode and move the contents of
/usr/ to whatever partition is free.
But it may be better to first try to clean out unused user files
out of /usr because there is for sure not 8GB worth of OS files that
would be there.
