that's actually less intuitive to me. it's not a printf() string
(since there are no arguments passed to it), but rather a format
string that gets filled in with specific values. look at it this way:
%s means "a string"
%d means "a number" (decimal, in fact)
%n means "name"
%p means "pid"
%u means "user" (or presumably uid, if curproc->p_session->s_login is
makes more visual sense. it might be fun to extend the %[npu] fields
with things like d (for a number, always, as in %u), o or x for the
pid (making it %xp), etc. maybe even add %t for current time_t. then
i could have a coredump string of
so that none of my coredumps get smashed. or we could really go
overboard and allow a "core search path" that looks for the first
place it can actually put a core file.
heh heh. but the first point (about readbility and formats) still
stands, even if i did get a little carried away.
