Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

not to do this was intention.
in fact even to help newcomers.
because newcomers tend to just copy'n'past some command line,
and then later blame whomever suggested that commandline for any damage
that caused.

if however that newcomer found out by himself how to do what that
sentence suggests, ... well, you get the idea ;-)

btw, zeroing the first few k (say, 100k) would have been enough
to make the drbdmeta believe there is no usful data there and it
could proceed without harming anything.
