Order of Operations to Install
1 fetch
2 checksum
3 extract
4 patch
5 configure
6 build
7 destroot
8 install
9 deactivate
10 activate
11 clean
(I'm kind of thinking out loud here...)
Proposal:
What if we changed the order slightly, so we do steps 1-7 for all the
packages first, and then, if there are no errors, do 8-11?
"Why?":
Suppose we have pkg2 which depends on pkg1. If they both build fine,
then we're dandy. But if pkg2 fails, pkg1 is still installed. If
there are a lot of dependencies, it can be a pain to track them down.
If we separate the steps into two phases, then most breaks during the
installation (which mostly happen during 5-6, I think) won't leave
unneeded ports on the system (at least not after a clean command).
Thoughts?
