[Ovirt-devel] [PATCH node-image] allow for {, lib64} constructs in blacklist variables

[ I noticed that I'd never sent this message.
  The patch is already in, as part of the enable-SELinux-in-node series,
  and the comments about left-over python files are no longer relevant,
  since now the containing packages are properly removed. ]

I noticed that /usr/lib64/python2.5 and others were not being removed.
That's because they're listed like this in common-post.ks:

    blacklist_lib="/usr/lib{,64}/python2.5 /usr/lib{,64}/gconv \
        /usr/{,lib64}/tc /usr/lib{,64}/tls /usr/lib{,64}/sse2 \

Listing them like that is a good thing, but when attempting to remove
them, the parts in curly braces would not be expanded, and due to the
use of rm's -f option, there was no diagnostic.

Prefixing the $RM with "eval " solves the problem.

Tested by mounting the .iso and confirming that python2.5 is no longer there:

    sudo ../release/misc-scripts/mount-livecd.sh setup \
    test -d /mnt/livecd-tmp3/usr/lib64/python2.5 && echo FAIL

FYI, on the topic of eliminating python-related bits, there is an
additional 1.5MB worth of .py, .pyo, .pyc files that we can prune:

    find|grep -E '\.py[oc]?$'|xargs wc -c

I'll be removing those, too, one way or another.
