/usr/lib.

That's why /sbin existed, to hold executables like sh and mount that were
required to add /usr to the filesystem tree.

d sysdir /var 775 root sys 1 NULL NULL
s sysdir /bin=/usr/bin
s sysdir /lib=/usr/lib
s sysdir /shlib=/usr/lib

note that /lib (and /bin) are symbolic links to /usr/lib and /usr/bin.
