: On the symlinks issue:
: Suppose instead of the current shortcut hybrid scheme, and also instead of
: copying the executables, and also instead of using NT-only hardlinks (which
: IIUC aren't Unixoid enough to be "drop-ins" anyway), "Somebody" wrote a
: "symlink.exe" executable that worked sort of like this:
I happen to have a program I call ``wrap''...
: - A suitable centralized alternatives database would be kept somewhere, with
: entries of a "/bin/ls == /bin/alternatives/actual-ls.exe" nature.
It (my ``wrap'') uses files in "/etc/wrap/" + basename(argv).
: - The "symlink.exe" program would be a one-pager that you copied, under the
: "assumed name" of the exe you're trying to symlink. So, as the /bin/ls.exe
: executable, it would:
My current wrap.exe is 4096 bytes, after stripping.
: - See that it was executed with the name "/bin/ls.exe"
: - Look up "/bin/ls.exe" in the database to find which real executable it
: should run.
The name of the executable to execute is read from /etc/wrap/ls.
: - spawn() that real executable.
My ``wrap'' uses execvp()...
: That would solve the "can't run it from a windows command line" problem,
: wouldn't it?
Absolutely. (I've been using this for unison for a while now.)
If there is interest in this, I'll happily ``ITP'' it...
Just let me know.
