>Description:
file(1) does not work on 68010 systems because cannt mmap the compiled magic file:

icarus# file /netbsd
file: cannot map `/usr/share/misc/magic.mgc' (Cannot allocate memory) (No such file or directory)
icarus# ls -lh /usr/share/misc/magic.mgc
-r--r--r--  1 root  wheel   10M Jul  6 22:29 /usr/share/misc/magic.mgc
icarus# 

The total address space limit on 68010, of course, is 16MB, and mmap'ing a 10MB magic file just won't fit along with everything else.
>How-To-Repeat:
See above.
>Fix:
For constrained systems, split the single magic file into separate files?  Christos aluded to this being a possibility.
