>Description:
fdisk on blank disk fails if /usr/mdec/mbr nonexistant

This occurred while trying to partition a disk from a trimmed
memory disk that did not contain /usr/mdec/mbr nor needed
to install boot code.

>How-To-Repeat:

# dd if=/dev/zero of=/dev/rwd1d count=100 bs=64k
100+0 records in
100+0 records out
6553600 bytes transferred in 0.198 secs (33098989 bytes/sec)
# /tmp/fdisk -v -u wd1
fdisk: primarypartition table invalid, no magic in sector 0
fdisk: /usr/mdec/mbr: No such file or directory

>Fix:

Not sure, but code inspection reveals that init_sector0 passes 1 to
the err_exit parameter of read_boot in fdisk.c
