[linuxsh-dev] nfs file system

[akira <aki...@ho...>]

=20

Hello to all,




now my kernel work, but I do not succeed to mount a NFS filesystem.




On the host computer work: portmapper, mountd, nfs. I have shaped also =
the file export.




What means:




VFS: Cannot open root device "nfs" or 00:ff

Please append a correct "root=3D" boot option

Kernel panic: VFS: Unable to mount root fs on 00:ff




What I can make in order to make he to work correctly?




Which are the options that I must choose in menuconfig in order making =
to work the kernel with a NFS filesystem?




Thanks!
