[Bug 1110331] Re: nscd no longer needs to be restarted by libc's resolvconf update script

[Thomas Hood]

** Description changed:

  Browsing the eglibc mailing list archives I notice[0] that the eglibc
  resolver has been enhanced[1] such that if /etc/resolv.conf's mtime
- changes then the client is asked to re-initialize the resolver state. I
- haven't tested the code, but if I understand the feature correctly it
- gives us an opportunity to eliminate from /etc/resolvconf/update.d/libc
- the code that restarts nscd after an alteration in resolv.conf. That
- would be a beneficial simplification. Ditto for some other resolvconf
- update scripts.
+ changes then the client re-initializes the resolver state.
+ 
+ This feature gives us an opportunity to eliminate from
+ /etc/resolvconf/update.d/libc the code that restarts nscd after an
+ alteration in resolv.conf. That would be a beneficial simplification.
+ 
+ Possibly ditto for some other resolvconf update scripts.
  
  Can we take advantage of this eglibc enhancement in order to simplify
  resolvconf update scripts?  Do we want to?
