Hm, the last time I looked a header used by kernels had space
for someting like 27 or 29 drives (I do not remember the exact
number) but its variant in 'raidtools' sources allowed indeed
only 12.  Synchronizing those headers to kernel values raised
a maximum number of disks in an array quite considerably.
