Hey misc@, I wrote a quick little tool here: https://github.com/neutralinsomniac/obsdpkgup in Go to show available package upgrades from your configured mirror.
It takes no more than a few seconds (the time it takes to download index.txt from the package repo) to show you all packages that have received a version bump. This tool *won't* show same-version package-rebuild upgrades, so it shouldn't be used as a complete replacement to running 'pkg_add -u', but rather as a companion to show when actual newer versions of packages are released. I just noticed that in my 99% case, I was waiting anywhere from 5-10 minutes for 'pkg_add -u' to complete checking all ~400 of my installed packages, and it uses a considerable amount of bandwidth while doing so. As I understand it, the pkgtools detect same-version rebuilds by downloading enough of every installed package tgz to check the metadata contained within to determine if an upgrade is needed. If anyone knows of an alternative way to determine when a same-version package install is required, I would love to know of it. In the meantime, I hope someone else can make use of this tool as well. Thanks! Jeremy
