[OpenWrt-Devel] glibc finally fixes /etc/resolv.conf handling

[Philip Prindeville]

For everyone who has ever wondered why they need to stop and restart long running services when they move from one network to another (as is common for laptops using Wifi that are roaming around), this can be quite vexing.

The reason was that /etc/resolv.conf would get rewritten by DHCP when you acquired a new DHCP lease, but programs which were running wouldn’t have sufficient knowledge to force the resolver to re-initialize itself (and arguably, they shouldn’t have to… it should just work).

This FINALLY (after many years) got fixed today:

https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=aef16cc8a4c670036d45590877d411a97f01e0cd

So, hopefully that will make life easier for people who support their WiFi users and will no longer have to say, “Have you tried stopping and restarting the service?”

Woot woot!
