Matt Oswalt has an article called ESXi vSwitch Load Balancing Woes where he deep dives into VMware's ESXi virtual switch and, based upon personal experience, discusses port channels, hash algorithm selection, and path selection. I need to refer back to this to see if networks I've seen conform to what he discusses.

Listing Package Dependencies
From How do I find the build dependencies of a package?, there are some commands for finding build package dependencies:
- full list of dependencies: apt-rdepends --build-depends openoffice.org
- dependencies not installed: apt-rdepends --build-depends --print-state openoffice.org | grep NotInstalled
- dependencies for top most package: apt-rdepends --build-depends --follow=DEPENDS
- show control file for source: apt-cache showsrc
| grep ^Build-Depends - show control file for source: apt-cache showsrc
