Now that the new rebase is out, I'm going to create an _autorebase
package which will automatically call rebaseall at the end of a
successful run of setup, if that run also updated existing DLLs or
came with new DLLs.
In some cases this might take two minutes or so at the end of a setup
run, but at least we should see less rebase problems in future.
The most efficient way would be to change rebaseall so that only
DLLs are given to rebase which are updated or new. But rebaseall
would still have to search the files in /etc/setup. And rebase
still opens every DLL in the DB and from the command line to see
if the DB and reality are still in sync, and to decide which DLLs
have to be rebased and which are not. So I'm not sure you can
make it much faster, unless you make the algorithm in rebase itself
faster. You're welcome to send patches to the cygwin-apps list.
I'm pretty sure there is room for improvement.
Needless to say that the ultimately most efficient way would be
to find a method to avoid rebase problems after fork at all. The
last attempt at it looked promising at first, but then again...
