Dunno who's the best person to tell this. The -a option to opiekey(1)
is supposed to suppress password checking, but closer inspection of
the code reveals that the value of `aflag' is properly set when the
option is provided, but then never used again. This prevents opiekey
from becoming a full replacement of the old skey program for users who
used to have too short secret passwords.
We should either remove it completely if we think providing this
option is a bad idea from the beginning, or make it work as
advertised. The patch below implements the latter. (Btw., the check
against (flags & 2) isn't useful either since flags is passed from the
caller as either 0 or 1, hard-coded. We could set flag 2 when aflag
is set, but that'd mean to modify 6 calls to opiereadpass() instead of
a single line of change as suggested below.)
