OK. I've never built the bridging part of the book's qemu (I already had a working nfs server where I store my sources and notes), and I haven't *used* qemu for some months. But when I last used it, no special actions seemed to be needed in LFS (i.e. mounting /sources in nfs v3 without forcing a version just worked. Unfortunately, almost nobody here uses nfs. I recall the first time nfs4 deps bit me, and I think it was some months before somebody came up a suggestion for how to fix the problem in a better way than whatever I was doing. Looking at my notes shows I was using vers=3 in /etc/fstab in 2010 and 2011, when nfs was i nthe 1.2 series. > I did not compile against any of the blfs optional dependencies only > libtirpc and I aslo tried with and without the "mount.nfs4" symlink. > > John Sorry I cannot add any useful suggestions. Looking back at my notes, when I moved to lfs-7.0 in November 2011 I had a *lot* of trouble with this, and apparently mounts worked only if, after booting, I "bounced" (i.e. stopped and started) the nfs server. At that time, I think I was still building libnfsidmap even though I only wanted v3. Looking at my git tree for my buildscripts, I can see that I finally removed 'tcp,vers=3' from /etc/fstab on desktop machines in May 2014, with a note that they are negotiated in current versions, but I have no idea what change caused me to do that. The only other thing that comes to mind is the kernel config on the server.
