Just some quick ideas - I haven't tried these, so they might not work:

1. If the /usr directory still exists you can umount /user and mount
   the partition on /usr, since /sbin/mount and /sbin/umount should be
   statically linked.

2. You can always use the builtin echo in /sbin/sh to overwrite
   /etc/vfstab, then /sbin/sync 3 times and power cycle.

3. How about setting LD_LIBRARY_PATH to /user/lib, then exporting it
   and using /user/bin/cp or /user/bin/vi?  ( This might not work,
   since on some systems, e.g. Ultra 20, most dynamically linked
   executables appear to have a dependency on
   /usr/platform/.../lib/libc_psr.so.1, whereas on others, such as
   SS5s, they do not)
