        You're not the first person to suggest this might be the culprit.
        But, /tmp remains the same both in single- and multiuser modes;
        notice that I was dumping /usr, and this output:

        roman@isis ~ 1003:2 > ls -l / | grep -Fe '->'
        lrwxr-xr-x 1 root wheel 10 Mar 18 02:08 compat -> usr/compat
        lrwxr-xr-x 1 root wheel 8 Mar 18 02:08 home -> usr/home
        lrwxr-xr-x 1 root wheel 7 Mar 18 02:08 opt -> usr/opt
        lrwxr-xr-x 1 root wheel 11 Jun 27 14:27 sys -> usr/src/sys
        lrwxr-xr-x 1 root wheel 7 Mar 18 02:08 tmp -> usr/tmp
        lrwxr-xr-x 1 root wheel 7 Mar 18 02:08 var -> usr/var

        IOW, if /tmp has enough space in multiuser, what would it cause
        to shrink in singleuser? (I tried the dump|restore multiple times
        in both modes, with consistent results.)
