  To help answer that question, on my x86_64 glibc build:

3.0M    /tmp/lvm2-app-library
2.1M    /tmp/lvm2-full-suite
472K    /tmp/lvm2-minimal


  So the app library adds another 40% to the package size. I guess that's 
significant enough not to remove the existing option. Especially because 
the only reason is that we can't find a better name for it :-)

  My original name was "install all binaries", but I found that less 
descriptive than "full suite". Maybe "install all LVM2 programs"?

  I could also copy the full list (which is in the .mk file) to the help 
text.

  Regards,
  Arnout
