Description Mathias Weigt 2011-03-03 08:56:53 UTC

I wanted to step up with my 30 netbooting Clients to use NFSv4 as I thought this seems to be matured now over the last 5 years. Unfortunately with genkernel generated ramdisks this seems to be impossible. I tracked this down to busybox but as far as I understand busybox mount can't do NFSv4 - even in the newest version. So I'm stuck up here. Maybe the regular nfs-utils could be somehow integrated into genkernels ramdisk?

Reproducible: Always

Steps to Reproduce:
1. Set up netboot system which boots root file system over NFS
2. Switch Server to NFSv4
3. Try to boot over NFSv4

Actual Results:  
You get either "Protocol not supported" or "denied by server" Messages (because the server now uses a new exporting scheme)

Expected Results:  
genkernel should support root file system over NFSv4

I tried the newest genkernel (3.4.13) and the newest busybox...
