This is correct. Its a similar problem with NFS. We need a nopage mount
option to force code pages to local swap for such devices. I find some
things keep well on CD-ROM notably little used stuff like TeX fonts
and ghostscript stuff.

For Linux doing none to smart (initially) SMP is being played with at the
concept level here (pending possible hardware donations). Some other people
'viper' are working on making the Linux kernel truely threaded but that is
a much bigger project.

I called Digiboard about there ISDN board and asked if they supported

why did not support and they told me they had seen the demand for it.
They where planning on a SCO driver.
So, I think everyone should, on principle, call Digiboard and tell them
that they want this support.

What I do is sell support! And my main problem is that MS makes the general
public believe that they may use a computer as easy as a TV-Set (some may not
even handle that correctly) wich simply is not true!
So people (even ones in the big offices, with a real world window =B-) )
see the bright colors of Winsnooze and of the double paged MS ad in their
paper. They send someone to buy it, not asking if the printer even works with
Windows. Than they curse Computers in general and are not wiling to pay my
prices and especialy are not happy if I have to tell them, that because of
their special needs, the MS office bundle has to finds its way to the dumpster.
People don't need to to know about waitstates. But if they don't they should
ask a technician to set the channels on their TV-Set.

That sounds like a good idea. Actually, the NFS automounter works
that way. Can it be changed to handle floppy mounts as well?
Also unmount after 90 seconds of inactivity or when all files are closed.

I can rephrase this slightly to make it more accurate with regard to DOS
software.
"
So if people seem to want their DOS software maybe it's because they
know if they like it or not. Something they have never seen before is
a little harder to trust until they've had a chance to bootleg a copy
and run it for a year or two. Bootlegging useful commercial software
is very hard in the UNIX world.

Microsoft bitches about bootlegging, but it has made them the company
they are today.

This SHOULD go away after a "mt -f /dev/rft? erase", if not,

as this seems not to exclude/mark bad blocks (??); with my old pc-tools 7.1

When you find & build it, be aware that there is a compile time option
in RCS-5.6.0.1 which is not documented, though it used to be in an older
version. I've let the authors know, and they say that they'll document
it in the next release, but until then...
In the man page for rcs, it says:
-L Set locking to strict. Strict locking means that the
owner of an RCS file is not exempt from locking for
checkin. This option should be used for files that are
shared.
-U Set locking to non-strict. Non-strict locking means
that the owner of a file need not lock a revision for
checkin. This option should not be used for files that
are shared. Whether default locking is strict is
determined by your system administrator, but it is nor-
mally strict.
As the system administrator, to make the default locking non-strict, you
need to add "-DSTRICT_LOCKING=0" to the CFLAGS in the Makefile before
compiling.
Cheers,
Dave.
