The man-pages are not a problem (really I had forgotten about it), the difference only is, that it lasts a bit longer to view the manpage allways, not only the first time - no errors. For a machine which has a dedicated role and you haven't to do a lot of changes, this works optimal, no fscks on / and /usr, very quick boot times.
