KEY_MAGIC should be changed

[ghost]

You removed the compression of keymap binary files. The format of the binary file has been changed, but not the magic identifier:

minix/minix/include/minix/keymap.h

Line 167 in 4db99f4

#define KEY_MAGIC "KMAZ" /* Magic number of keymap file */

The original one was KMAP and it was renamed to KMAZ when the compression was implemented. Now you have removed the compression, but not the magic key. I do not know if it is still the same as the original implementation (Minix 386vm). May be KMA330 would be a suitable magic key.
