Linus claims to have maintained *BSD compatibility, though he
wrote the functions himself:

"Ok, I did my own versions, since (a) I had already started and your
patches wouldn't apply, and (b) I hate adding a zillion lines of extra
copyright notices for a 5-line function..."

(strlcat was added as well)

I dont think strcpy is the main target, as much as strncpy. Linus again:

"Yeah, "strncpy()" is a frigging disaster when it comes to '\0', in many
ways. We should probably disallow using strncpy(), and aim for a _sane_
implementation that does what we actually want (none of that zero-padding
crap, and _always_ put a NUL at the end). I bet that is what most current
strncpy() users actually would want."

A light grep of 2.5.70 shows many uses of strlcpy, strncpy, and strcpy
out there...
