uh yeah..  if it had been marketed better, say 5 years ago or more, it 
might not be in
the same position it is now. Its a fine OS for what it does.. Its fairly 
old school though
as you know.. Not a nice whiz=bang OS.. although, have gotten pretty 
good at compiling
stuff for it.. icewm, fvwm, etc.. works pretty well...

but to the point-

Im thinking about this a little more.. One problem that the particular 
OS with the dwindling
market share has is this:

*IF* you have a memfs setup in /tmp and your app's use /tmp quite abit.. 
It is possible to fill
that sucker up.. So think about sizes when building /tmp give yourself 
enough space.

One trick we need to employ sometimes if folks create a /tmp memfs that 
is too small is to unmount it
and leave it dangling on the rootFS during installs of packages 
especially. Then remount it as memfs..

have fun!
