Told you I wasn't familiar with xargs :-)  I really need to spend some
time and get more comfortable with it.

I ran into this becuase gzip was complining that a file had "too
many links" to compress.  It also forces compression when the
resulting output file already exists.  I was running into the
first problem - e2fsprogs installs some man pages, then creates
hard link to some of the man pages under a different name.

I'll be honest in that I'm not positive this is the right thing
to do in these situations ().  If I understnad things correctly,
the warning is there to let you know that you're breaking a hard
link; but I'm not sure that's really an issue, aside from creating
a slightly larger binary package.
