Cannot open "/dev/ad0" on -CURRENT

[Craig Rodrigues]

Hi,

I debugged some more, trying to figure out why I could not
add a new partition to my disk using /usr/sbin/sysinstall
on -CURRENT.

I tracked the problem down to these lines in libdisk's write_i386_disk.c:

     98         strcpy(device, _PATH_DEV);
     99         strcat(device, d1->name);
    100
    101         fd = open(device, O_RDWR);
    102         if (fd < 0)
    103                 return 1;

According to the debugger, device == "/dev/ad0"

I wrote the attached program to open "/dev/ad0".

It consistently fails with:
fd: -1
Error: : Operation not permitted


If I change the program to open one of my SCSI disks, "/dev/da0", it
does not fail:
fd: 3

Any ideas what the problem could be?

Thanks.
