Attached is a patch that adds the rebase functionality to setup.exe. I would like to get some feedback before I start to resolve the following issues: o How to handle a missing config file (i.e., /etc/setup/rebase.conf)? o Need to handle in-use files. o How to handle corruptible (by rebasing) files? o How should dependent DLLs be handled? and some other more niggling items. I re-installed 30 out of the 33 packages that contain DLLs and my system is functioning normally. Python can even fork too! I only skipped curl, postgresql, and rxvt because the DLLs contained by these packages get corrupted by rebasing. If you would like to test out a setup.exe which includes the rebase functionality, then a pre-built version is available at: http://www.tishler.net/jason/software/setup-rebase/setup-rebase-2002-02-02-1.exe Before you run this setup.exe, you should download the default rebase configuration file: http://www.tishler.net/jason/software/setup-rebase/rebase.conf to /etc/setup. I also have a stand-alone rebase.exe that I would like to contribute to Cygwin so that users can rebase without having to run setup.exe. Here is the current usage statement from rebase.exe: usage: rebase [-i|-r|-u] [-d CygwinRootDir] ImageFileName ... where: -i => install ImageFileName(s) -r => re-install ImageFileName(s) (default) -u => uninstall ImageFileName(s) -d => set Cygwin root directory (defaults to ".") A pre-built version of rebase.exe is available at: http://www.tishler.net/jason/software/setup-rebase/rebase.exe I see the following uses for this program: o makefiles o resync system (hopefully never needed) o used by a one-shot converter script The following is an example of a postinstall script, rebase.bat, that could rebase the entire user's system without have to reinstall "everything": gzip -d -c /etc/setup/*.lst.gz | grep "\.dll$" | sed "s=^=/=" | xargs -n 1 cygpath -wa >rebase.tmp rebase -r -f rebase.tmp del rebase.tmp The above assumes that I have added a "-f" option to rebase.exe and changed the default value for the "-d" option to be the Cygwin root directory obtained from the Registry. Any feedback on the above would be greatly appreciated. Thanks, Jason
