You would get the same problem with NFSroot on a real hardware. > A prime example is the "tar" testsuite which is very picky about > filesystem behaviour. > - With a real ARM CPU building on local (USB) storage, it passes all tests > - With a real ARM CPU over NFS the testsuite fails one test (cyclic renames) > - From QEMU in a locally-mounted nfsroot it fails a dozen tests. > - Building with QEMU in an NBD volume passes all tests. > > What do your QEMU buildds use for mass storage? I use aranym (for m68k) and a 14Gb real hd partition. I tried to use NFS but given up due to the issues you mention and poor performance.
