missing disc space

[Lloyd J. Lacomb]

Now that the debug partition seems to be well understood, I am still puzzled
by the missing space on the disc.  I have a 380 Mb disc, and when I do a df
I get the following:

Filesystem                  Type kbytes    use  avail %use  Mounted on
/dev/root                   efs   15591   9504   6087  61%  /
/debug                      dbg   58196   5508  52688   9%  /debug
/dev/usr                    efs  236529 132029 104500  56%  /usr
-----------------------------------------------------------------------
TOTAL                            310316

My question is if df reports only 310 Mb including the swap space what
happened to the 70 Mb (plus or minus the 8 Mb of core memory) that my disc 
is supposed to have.  I know that df does not count correctly and that 
a 380 Mb disc does not really have 380 Mb(what a racket!!!) but it
still seems that I'm missing a lot of Mb.  I used to think that most 
of the missing Mb was occupied by the swap space but that appears not to be 
the case.  Can anyone clear this up.
