>Description:
/bin/tar (and /bin/cpio) depends on /usr/lib/libarchive.so
they won't work unless /usr is mounted if it's in a separate
partition.

>How-To-Repeat:
% ldd /bin/tar
/bin/tar:
        -larchive.5 => /usr/lib/libarchive.so.5
        -lbz2.1 => /usr/lib/libbz2.so.1
        -lc.12 => /lib/libc.so.12
        -lcrypto.15 => /lib/libcrypto.so.15
        -lcrypt.1 => /lib/libcrypt.so.1
        -lgcc_s.1 => /lib/libgcc_s.so.1
        -lexpat.2 => /usr/lib/libexpat.so.2
        -llzma.2 => /lib/liblzma.so.2
        -lpthread.1 => /lib/libpthread.so.1
        -lz.1 => /lib/libz.so.1

>Fix:
No idea about our current policy.
