Others have clarified the 9K Logical Blocks vs 18K 'physical blocks'
(a.k.a. sectors) confusion.

I would strongly recommend *NOT* doing multiple partitions!
"YOU" there -- yes, YOU with the 20 MB disk -- STOP THIS!!!!
Good grief, the instant guru virus has struck again, and pholks
all over are doing things that weren't recommended or intended
by the manufacturers -- and they'll blame AT&T for their problems.
1) The 3B1/7300 was designed for SMALL disks. Philosophical error,
here -- we ALL blame SOMEONE for that -- but we must live
with the results. Specifically, BECAUSE it was
designed for a single, small disk, the folks who wrote
INSTALLATION DISKS were not prevented from developing
techniques that REQUIRE '/' and '/usr' to be on the same
file system. Are you going to put ALL the OS software
in 9 MB? Really a bit cramped, aren't we?
For anyone with disks smaller than 60 MB, I'd strongly
recommend using only a SINGLE large partition. Make a
SMALL (10% of total) second partition if you JUST MUST
walk on the wild side! Otherwise, someday you'll find
you want to ADD a package, but the SPACE is on the
wrong partition.
2) I HAD a 147 MB MX2190 -- R.I.P. -- which I broke into
5 partitions, and tried living with a mounted /usr.
Could NOT take it after 2 months: every other package
I received took hours and hours to TRY to re-configure.
EVEN IF YOU HAVE AN **ENORMOUS** disk, save yourself
mountains of aggrevation by NOT MOUNTING /usr.
OK: I have MORE packages at hand than most of YOU...
but I've ALSO more experience with UNIX and STILL
couldn't take the problems -- and the grating little
ones you wouldn't even see for weeks! YETCH
