trouble installing help2man on new gentoo box--Solved: too fancy with symlinks/mounts

I was thinking of reading the details of bind mounting, but decided I
spent/wasted enough time trying to have a "clean" system with all
mounting at /mnt. If your suggestion meant that usr would be mounted at
both / and /mnt, I don't see that as any cleaner than having it just at /.
If the purpose was to "document" all the mounts by having them at /mnt,
I could do that with a symlink
ln -s /usr /mnt/usr
I still feel it is somehow "cleaner" to have all mount points be
in /mnt, but am cutting my losses.
thanks for the suggestion.
