|
|
# This program examines the contents of the DOS filesystems and
|
|
# attempts to generate a sensible wine.conf file. This is output
|
|
# to STDOUT.
|
|
# It reads /etc/FSTAB to find mounting locations of the hard disk drives
|
|
# It uses the correct algorithm for ordering DOS drives, with the
|
|
# exception of the case of multiple drive controller types, where I don't
|
|
# know what DOS's algorithm is.
|
|
# It uses find to find all of the win.ini files on any DOS partition
|
|
# and sorts them by age to guess which is part of the active Windows
|
|
# installation.
|
|
# It reads the autoexec.bat file (if found) and records all variable
|
|
# settings. There are some inaccuracies in its determination.
|
|
# First, while variables are interpolated properly, no control
|
|
# structures are supported so calls and execs to other batch files are
|
|
# ignored, and all variable settings take effect regardless of whether
|
|
# they would in DOS (i,e., both if and else clauses are read).
|
|
# This is used to determine the path and temp directories. Duplicate
|
|
# path directories and path directories that don't exist are thrown
|
|
# out.
|
|
# On failing to find C:\AUTOEXEC.BAT, wineconf finds all executables
|
|
# in the windows directory and subdirectories, and generates an
|
|
# optimized path statement encompassing all the executables.
|
|
# Then it also looks for \TEMP and \TMP on all drives taking the first
|
|
# one it finds.
|
|
# wineconf doesn't support floppy drives, network drives, printers,
|
|
# and serial device configuration is hardcoded and not configured for
|
|
# the machine it runs on. Similarly, spy parameters are hard coded.
|
|
|
|
# It would make sense to incorporate much of the hueristic code in
|
|
# this program into a library to be shared with a dosemu configuration
|
|
# program, because it seems that at least some of the same stuff will
|
|
# be wanted. The program needs to be cleaned up still. A better tmp
|
|
# search algorithm could be written. A fast option is planned. Less
|
|
# Linux-dependence is desired. Should look for devices independent
|
|
# of /etc/fstab; then sanity checks on /etc/fstab can be performed.
