i will be either creating a SYSKEY-like algorithm (and to hell with anyone
who thinks it's an implementation of microsoft's reasons why syskey is
used, that's NOT why i need it)
or creating an equivalent of /etc/shadow
or just giving up because i'm fed up with having to explain things in such
detail when it hurt like hell to just damn well type.
or just not explaining it, just getting on with it.

yeah? and?? so my job is made easier by mapping to the best
unix-file-sec i can and special-casing everything else.
and?? what's the problem?

actually, i will need two per user (passwords and everything-else).
and you need... so far, i count about 16 separate single-key databases to
hold a full SAM database implementation.
that's if you don't go for a file-per-user, file-per-group,
file-per-alias, file-per-user-members, file-per-group-members,
which i'm considereing
in which case, you have to hold these in directories else it's a mess.
see HKLM\SAM\... for details.

right now, i don't want to have to do that.
