rocklinux/package/base/mine/x-feature-check.patch

I know that a:
md5sum --check var/adm/md5sums/$pkg

is sufficent for the check task - but a statically linked version for
rescue situations are a nice-to-have (ehrm yes - I had to solve some stability
problems on my iBook in the last days ....). Mine should be the right place
for a common package check interface.
