There is free Linux software called afpfs which allows a Linux machine to
be an AppleShare client. You can find a copy at the Netatalk HOWTO page
(http://thehamptons.com/anders/netatalk/), which also has a mailing list
and other useful information.
There is a company working on a MacOS runtime environment for LinuxPPC
called SheepShaver (http://www.sheepshaver.com/). This is not entirely
vaporware, as they already have a working product for BeOS. According to
their web site, they have made some real progress on the LinuxPPC version;
they even have a screen shot. No word on a release date, though.
Cordially,
Steven G. Johnson

When Red Hat (Red Hat pre-6.0 beta) switched to glibc2.1 Executor, our
application died. Initially I thought this was due to glibc2.1, but
later I realized that when they switched from gcc to egcs, the calling
conventions for returning a struct that is greater than 32 bits
changed. That meant that our code that used the shared db library
broke.
So although it's not a glibc2.1 issue, I expect there will be other
apps that were compiled under gcc that use the shared db library
(because staticly linking in the db library violates its license) that
will die if the db shared library is compiled with egcs.
In fact, it's possible for the calling convention difference to result
in code that only intermittently dies, depending on exactly when
signals get sent to the process.
Once I found out what was wrong, I was able to wrap the db calls in
such a way that they can use either version of the db shared library,
so we now have one Executor executable that works with both.

This is probably the best option - LinuxPPC is pretty solid, MKlinux
(easier to install?) is a bit sluggish as it runs on top of a Mach
microkernel instead of natively but is a decent port of Linux nonetheless.
Me, I'm looking forward to Sheepshaver (http://www.sheepshaver.com) MacOS

The good news is that in Linux, you change /etc/fstab to have the new
letter for the drive, and all your filesystems are again mounted at the
right spot. Under DOS/Win, you need to change your PATH, registry, many
many places that have the drive letter. Linux is still better.
However, my idea for Linux LVM is to have unique ID on each drive, and
at startup scan drives for ID, and not use "device name" at all, doesn't
matter then if you change SCSI ID or even adapters - it will still work.
This is how AIX does it - you can randomly change any drive locations
(except boot drive), and everything works without any config changes.

??? PPP requires a clear text channel to send data over. no such channel

In fact, if you do a "shutdown -f <other opts>" (ie fast startup), then
the fastboot file is created for you, and it won't do an fsck on the
filesystems, no matter how they are set. If you are doing a
maintenance reboot in a small time window and you want to make sure
that it goes quickly, then use the "-f" flag. If you have the time and
want to be safe, then leave the "-f" out of shudown and it will check
the filesystems which "need" it.

You can add dynamic socksification (runsocks) to the list...
Neither NEC socks, nor DANTE work with glibc-2.1 in dynamic mode!
These work if an app is recompiled, its just the dynamic aspect
doesn't work... Even when these libs are compiled with glibc-2.1

What versions of Linux are available on Mac? I've heard of
MkLinux and LinuxPPC but not much else. Does LinuxPPC use
the same kernel as X86 versions? Are there X-compatible
free windowing systems available?
Thanks a lot.

I think he meant a graft on top of a graft. Still, curiously mixed
metaphor there...
The thing that worries me with this kind of reasoning is that there's
so much software which - for better or worse - is controlled by CVS,
that it will be damn near impossible to get people to switch. Sort of
like the FORTRAN or COBOL of version control. One possibility could be
to start by redesigning the repository database, while maintaining the
current CVS command set. Then add improved commands. [And, no, I'm not
the one to do it].

Subject: mknod from a module
Date: Mon, 03 May 1999 17:39:53 GMT
Hi,
I am trying to call mknod from a module. Currently I do something like the
following:
int (*mknod_call)(const char*, mode_t, dev_t);
...
mknod_call = sys_call_table[__NR_mknod];
err = mknod_call("/dev/name", S_IFCHR, MKDEV(123, 1));
This comes back with -14 (EFAULT - bad address). Does anyone know why it
fails? I guess the string address is bad maybe because it does not originate
in user space ...
In general can I make system calls from the kernel and if so how?
Thanks much for any help.

So is g++.
egcs (now the official GCC) has been far better than this at template
instantation from day one.

The problems that develop on floppies in storage (unreadable sectors)
are not the file system inconsistancy problems that e2fsck detects and

(a rather small fraction of the space on the disk), e2fsck won't detect
