Normally -- well thought out high availability systems have both a failover box and a backup site - a "sister" site with the same species of box that would allow you to run your mission critical app until the flood waters receded.

It's not even remotely practical to try something like that - how would you capture the registers? The PC (program counter) register would not mean anything, for example, going from a Sparc station to Linux running on a PC, for example.

If this were a reasonable choice, wouldn't you expect that big companies with mission critical apps would be doing something like this routinely? No company does a cross-platform thing like this - AFAIK.

NAME
clean-binary-files - remove a third party binaries (JARs) from an upstream archive SYNOPSIS
clean-binary-files {[-f {-, instructions_file}], [-e exclusion_file] [-l]} [-a archive_file] [-d custom_jar_map] [-n] [-p] [-s] OPTIONS
-f The instructions file, specifying which files to keep and which to remove -e The exclusions file, specifying special binary files that are to be preserved, or non-binary files that are to be removed. -l Only list instructions (to put in instructions file), do not delete anything. -a Archive file on which actions will be performed, as opposed to current directory -d A custom jar map file (has priority over the generic one). -n No symlinks (i.e. only clean jars, don't run build-jar-repository afterwards) -p Preserve original file names (-p to build-jar-repository) -s Silent mode. Won't output commands during cleanup -f The instructions file, specifying which files to keep and which to remove -e - The exclusions file, specifying special binary files that are to be preserved, or non-binary files that are to be removed. -l - Only list instructions (to put in instructions file), do not delete anything. -a - Archive file on which actions will be performed, as opposed to current directory -d - A custom jar map file (has priority over the generic one). -n - No symlinks (i.e. only clean jars, don't run build-jar-repository afterwards) -p - Preserve original file names (-p to build-jar-repository) -s - Silent mode. Won't output commands during cleanup EXAMPLES
Suppose there is a vanilla tarball abc-1.tar.gz with some binary files (jars) in it. In the source repo, we would want a clean copy without any jars. We can use the scripts to achieve this: To generate an instructions file: clean-binary-files -e <exclusion file> -l -a abc-1.tar.gz > instructions This creates an 'instructions' file, which contains info on what stays and what goes. Then, one can run: clean-binary-files -f instructions -n -a abc-1.tar.gz This would create abc-1-clean.tar.gz for uploading into jpp/fedora/etc. repositories with no binary (jar) files. Alternatively, if you have a vanilla tarball, you can clean and create symlinks in it's place all at once by: clean-binary-files -e <exclusion file> -d <custom_jar_map> -a abc-1.tar.gz Note: If the -a <file> is not given to clean-binary-files(1), all actions are performed on current directory.
