Hmmm ... for an example, most data in the web2c/ directoy are
variable data (e.g. if a format is rebuilded), also the ls-R
files are variable.

only /usr and all data therein should be usabel even if /usr
is mounted readonly ... even after texconfig was called ;^)

Hmmm ... in RPM language a `Conflict' means that you can not install
two conflicting RPM packages on the same system. And a package is
simply the read to install RPM file, which includes a cpio archive
together with informations about the files of the archive and
cross informations in comparision to other RPM file/packages
(dependcies, conficts, requirements).
See the attachments what I'm doing with the teTeX-nfs package to
import all what is needed.

TeTeX over NFS for Clients
==========================
Four steps are required:
* First (of all of the clients): Do not install any teTeX packages
but at least the package te_nfs.
* Second (on the server): Install the teTeX packages your need
and add the following 4 lines to /etc/export
/etc/texmf *.your.domain.here(ro,root_squash)
/usr/share/texmf *.your.domain.here(ro,root_squash)
/var/lib/texmf *.your.domain.here(ro,root_squash)
/var/cache/fonts *.your.domain.here(rw,root_squash)
and call
killall -HUP rpc.mountd rpc.nfsd
* Third (of all of the clients): Run the following command:
tetex-import your.tetex.server.here
with `your.tetex.server.here' the IP address or full qualified
domain name of your teTeX server.
* Fourth (of all of the clients): Add the four lines which the
script tetex-import has (hopefully) written to standard out
to the file
/etc/fstab

tetex-import \- Utility for teTeX integration over NFS
.SH SYNOPSIS
.\"
.B tetex-import teTeX_NFS_server

.SH DESCRIPTION
The script
.B tetex-import
helps at the integration of a remote teTeX
system into the local system over NFS.
.\"
.SS General Options
.TP
.IR teTeX_NFS_server
This is the name or IP address of the NFS server providing
the teTeX system.
.TP
.IR \-i
Integrate the teTeX system (default). After mounting
and setting all required symbolic links upto four
lines are written to standard out. These lines should
be added to
.BR /etc/fstab .
.TP
.IR \-d
Deintegration of the teTeX system. After removing
all required symbolic links and unmounting the teTeX system
a few lines are written to standard out. These lines
should be removed from
.BR /etc/fstab .
.TP
.IR \-o\ mount_options
Use these mount options instead of the default
.IR exec,nosuid,nodev,hard,bg,intr,rsize=8192,wsize=8192 .
.TP
.IR \-m\ machine_binary_type
Use this machine binary type. Default is
.IR arch-system-libc .
Some example: i386-linux-libc5, i386-linux-glibc.
