NetBSD icarus 11.99.7 NetBSD 11.99.7 (PHAETHON1) #154: Fri Aug  7 14:45:49 PDT 2026  thorpej@dhcp-105.ktnet:/Users/thorpej/NetBSD/current/src/sys/arch/hb68k/compile/PHAETHON1 hb68k
>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.

 Try:
 	cp -r /usr/src/external/bsd/file/dist/magic/magdir /usr/share/misc
 	rm /usr/share/misc/magic.mgc

 and see if that behaves better.

 Oops sorry, the directory in /usr/share/misc should be called magic not =
 magdir.
