First, disk space is _an_ issue but its not the over-riding one.
Assertions about what are and aren't install-tool issues coming from
non-install people should be taken with a grain of salt.


>Is all this concern about space warranted?  [snip lots]


Rob, I understand the arguments you made, they're good ones.  But only
if you have a new emachine or a machine that can handle new, cheap IDE
or SCSI disks.  They dont just hold for a microvax-2, or an SMD sun3,
or maybe even an MFM i386 (compared to the price of one.)
the price of a SCSI adaptor for these systems is comparable to the
cost of a complete new Pentium-II system-- if you cn even find one.

People do try and install NetBSD onto 80s and 90s systems which still
have their late-80s/early 90s disks: ~200M or so.  One well-known
developer comments from time to time about how NetBSD used to install
onto a 386 with 4M ram and 80M disk, and why can't we support upgrades
of machines like that?  ANd just today I got a message from someone
who didn't install X on a pmax becuase it wouldnt fit on his 200M
disk, and we dont have very good support for adding multiple disks in
at install time.

So.  Disk space crunch is _one_ of the drivers for pkg-izing the
install sets. That's a fact, even if its not applicable ot your setup.
Given that, checking for space is a reasonable thing to do if we can
do it easily, surely? Especially given how nastily things go wrong if
you run out of space during an install?

Yes, thats another nice feature of pkg-izing the sets.  obviously
disk-size checks is not important there, but it is for other uses of
pkg-ized sets.

Please take that up with the pkg people.  pkg-ized install tools will
just be using the normal pkg tools to install the pkgs in pkg-ized sets.
But yes, I think we should support something more tripwire-like.
