Actually, someone has. Your 'examples' are an indication of a sane
layout: program executables, libraries, program data and configuration
information are all seperated from each other. This allows for backup
of the configuration information ( dynamic, typically stored in or
under /etc ) while skipping program executables ( normally static,
stored under /bin ( needed for startup ) or /usr/bin ( the rest ) ).

X11R6 stores things in /usr/X11R6 because X11R6 isn't part of the
required system. /usr/X11R6 could easily be a seperate mount point,
mounted only on systems that actually needed the X11R6 programs.
Desktops could mount a complete X11 system, while servers might
not mount it at all ( having no need for a GUI themselves ) or mount
a smaller clients-only version.
One reason that GCC installs libraries in /usr/lib ( and an app-specific
directory under it used _only_ by GCC ) is standardization: libc.so is
_always_ found in either /lib or /usr/lib, and applications are expected
to use the version(s) there. Actually it's a slight misnomer to say
that GCC installs libraries there. The libraries belong to glibc2.x
typically, libc5 on older systems, and are used by both GCC and EGCS as
the standard C library.
And unlike Windows, Unix apps that install under /usr/lib typically don't
overwrite existing libraries and such belonging to other packages. They
install into their own directories, or use unique library names and version
numbers, and tell the package management system ( when one is used ) what
files they own so the admin can quickly ask 'Which package does this file
belong to?' or 'What files does this package own?'. For an app, an
attempt to overwrite an existing file not owned by a previous version of
itself is a fatal error during installation and almost always causes the
installation to fail without having installed anything.

At least on my system, I can tell the package manager where to root the
GCC ( or EGCS in my case ) tree during install, overriding the default
locations the package builder specified.

Well, most of the commercial software I've seen comes as .rpm ( RedHat's
package manager ) or .deb ( Debian's package manager ). I can readily
convert between most of the package formats I've run into, and at least
with RPM I can convert a tarball into a package with not overmuch work
once I understand the app's layout ( a prerequisite for installing it
in the first place ).

In case you haven't notice.
A new LILO, 0.21.4.2 has just been releasded, it supports up to
2Tb HD.
No more 1024 cylinder limit. Itsn't that wonderful? :)
Get it from

Uh, oh...perhaps there's more to this than meets the eye. I timed the
formatting
of 1.2M and 360K diskettes on the same high-density Teac drive
(FD55GFR-7193-U)
under Linux (RH 6.0) and DOS (with Win 98) on a Pentium II - 450 MHz system.
Linux DOS
1.2M 89 s 68 s
360K 46 s 33 s
With the factory jumper settings, the drive speed is supposed to be 360 rpm
for both high and double density. If the tracks on the 360K were written
two-by-two with the same data to emulate the wide head of a double-density
drive, one would expect the times to be approximately the same, but it
looks like only every other track was written. (The shorter times under
DOS are probably attributable to it verifying each track immediately after
writing, whereas Linux makes a separate verification pass.)
I also checked the jumper settings on my 10 year-old Teac FD55GFR-142-U
and they are the same factory settings, i.e., double-density speed is
360 rpm. This drive is installed on an old 33 MHz 486 system running
DOS 5.0 and the times for formatting 1.2M and 360K diskettes are
approximately the same as shown above.
The test diskettes were not bulk erased and the 360K diskette had been
previously written on a double-density drive.
Now I'm more confused than ever.

Charles Sullivan

Er, you probably mean "Windows Emulator" unless you're on a {Sparc,
PowerPC, MIPS, S/390} machine. But try--
http://www.winehq.com (free! may not work with everything though)
http://www.vmware.com (free trial, $100 or so for full version)
To use VMWare effectively, you must have the Other OS installed on a local
hard drive, and you should have a processor > 400MHz and 128M or more RAM
for decent performance. Lots of folks swear by it.

Sounds like the root partition has moved. Try entering
linux root=/dev/hdXY
where X is the drive letter and Y the partition number of your Linux root
partition. Or since you have a rescue system available, get in and edit
/etc/lilo.conf so the "root=" line for your kernel image points to the
right partition, then re-run LILO.

That is what it means (practically). Your distribution should have an
initlevel where the system boots into a graphical login screen. The
text consoles are still available, but the xdm login screen is what
you'll see after the system has finished booting. On my Debian box,
initlevel 3 gives me the xdm login. I know RedHat uses initlevel 5
last I check, and so does Slackware I believe. I don't know about the
rest.
I believe gdm (GNOME), kdm (KDE), and Login Manager (CDE) are all
derived from xdm, and operate the same way. The nice thing is, if
you're on network, xdm and friends allows you to choose to start an X
session on any machine on the network that is willing serve it up.

Most "sane" xdm et al. setups will kill the X server and start up a
new one everytime a session ends (the user logs out), allowing the OS
to reclaim any leaked memory. Since you're start x manually from the
command line, using xdm and friends won't be of much benefit,
especially if you spend most of your time in text consoles.
