Once you mv /usr/lib /usr/lib5, dynamicly linked executables will be
broken, until you mv /usr/lib4 /usr/lib (I think). I think it
would be a good idea check every tool you think you might need,
and build a staticly linked executable if the existing executable
isn't. Most of what you need will be staticly linked by default,
but e.g. sshd, ftp, find, vim, are not. (If all goes as planned,
you won't need any of those while /usr/lib is being moved, but
... ) (Caveat: this isn't based on experience with freebsd, it's
based experience with linux boxen, where *everything* is typically
staticly linked, unless someone rebuilt tools.)
