Hey Paul!

Errrrr ... what a mess!!!  I don't envy you especially with your penchant for
floppy boots.  You are even a bigger sucker for punishment then either myself
or Wayne.  That is really, really sad buddy.

So do I.  I don't have a monitor on anything that uses busybox so I really
don't need colour.  Do I?

Right.  I think the HLFS might be right up your alley but I'd just go as far as
building a chrootable development enviroment on a more capable system and use
that as a host to target the LEAF-Bering system.  I've never done that but then
again I never needed to before so that would be my best guess as how to go
about supporting it.

I agree.  Same with flash disks no matter what kind (usb, ide, scsi, pcmcia,
whatever).  That is the best methinks.  Personally I like having 8M ramdisks as
it leaves more elbow room then 4M (floppy) and is the best tradeoff or balance
between leanness and meanness.  4M is doable but a tad too limiting for my
liking.  8M is best methinks.  More then that is getting wasteful.

Understood.  I do it but so far all my targets have been simular (x86 based) so
it isn't that hard.  However throwing this EM64T into the mix, and the AMD64
just before that, really made things a tad interesting (still does) for a few
months there.  It finally is coming together though but I really have to be
more careful then I was in the past.

If you can successfully build a LFS system then I'd say you met your immediate
targetted goal.

I have no idea.  All my systems are glibc based.  So far that has proved to be
the best and easiest approach even for the busybox based systems which at the
moment is only the C3 guy (i686).  ttylinux can easily take care of it's needs
although I still have to provide my own vsftpd.  No scsi on that machine, only
usb which needs scsi generic in the kernel for mass storage devices on a usb
interface.  2.6 kernels work great on there but no floppy/CD/DVD drives so I am
less restricted then you seem to like to be.

Floppies died here over a decade ago.  It is a nonissue even to diskless
systems.

 PR> I don't want to start by wasting space.

Agreed but that has nothing to do with floppies.  Never has and never will.

Not in my case.  In the situation here keeping things in sync is of greater
concern and across the board that means glibc and at least ext2.  I see no good
reson to complicate the network here just to suit lousy floppies.  That is far
too crippling for my liking no matter how compact.  I like things to be
powerful and have found ways to keep it lean without resorting to stinkin'
floppies.  ;-)

Life is good,
Maurice
