[gentoo-user] Unable to start rpc-idmap after kernel update...

[gentoo-user] Unable to start rpc-idmap after kernel update...

[Tanstaafl]

Ok, I just need a sanity check...

I just updated my kernel from 2.6.37-r4 to 3.0.6, and now am unable to 
mount a remote nfs filesystem (on a QNAP NFS) that has been working fine 
for years...

I'm getting the following error:

myhost : Sun Dec 11, 12:20:00 : ~
  # /etc/init.d/rpc.idmapd start
  * Starting idmapd ...
  * make sure DNOTIFY support is enabled ... 
 
                  [ !! ]
  * ERROR: rpc.idmapd failed to start
myhost : Sun Dec 11, 12:20:03 : ~
  #

what is confusing me is I have never had DNOTIFY support enabled (I only 
enable INOTIFY), and I simply did a makeoldconfig when 
upgrqading/compiling the kernel, so why was it working before, but not now?

Do I really have to enable DNOTIFY now? If so, why did it work before?

Thanks...

Perhaps they fixed a kernel bug that allowed it to work despite the 
difference?  It wouldn't surprise me.

I've noticed that kernel config flags and "required ones" noted in 
Gentoo documents get out of sync rather quickly and they are fast-moving 
targets.  Go ahead and re-configure the kernel with the requested flags.

Maybe so...

Yeah, it's working now... thanks...
