Lazy Reading for 2019/08/18

Again, way behind cause of being online only irregularly over the last week.   There’s still plenty to look at – August is made for Lazy Reading. Never fast enough.  (Scroll way down)  There’s a nonlinear payoff for software speed … for tools. Related: Fast Software, the Best Software. Also related: Performance Matters. On the flip …

dhcpcd and DragonFly, continued

Roy Marples, the ‘upstream‘ for dhcpcd(8), noticed that DragonFly was working with it as a dhclient/rtsold replacement, but the process wasn’t complete.  So … welcome new committer!

zi0r suggested I use hooks to accomplish my patches-outside-distfiles question. In this post: FreeBSD 12.0 poudriere 3.3.2 I started reading the documentation and played with the supplied sample files in /usr/local/etc/poudriere.d/hooks. For background, see FreeBSD custom port patches when using poudriere. Eventually I came up with this solution: mkdir during the start phase mount during […]
