in gentoo nfsd filesystem is mount in /proc/fs/nfs, as many sources state nfsd should be mount in /proc/fs/nfsd This could lead to various behaviors. as a stupid example, one could check if a server support nfsv4 by doing cat /proc/fs/nfsd/versions | grep +4 it seems that everyone think /proc/fs/nfs is for client & /proc/fs/nfsd is for server Reproducible: Always Actual Results: nfsd is mount in /proc/fs/nfs ls /proc/fs/nfs exports max_block_size nfsv4recoverydir portlist versions filehandle nfsv4leasetime pool_threads threads ls /proc/fs/nfsd Expected Results: nfsd should be in /proc/fs/nfsd to be safer as a ref this http://bugs.gentoo.org/show_bug.cgi?id=25106 show that /proc/fs/nfs has been choosed to be the mount point (see comment#1) base on a document from www.citi.umich.edu. but at www.citi.umich.edu they tell to implement it in /proc/fs/nfsd some sources http://www.citi.umich.edu/projects/nfsv4/linux/using-nfsv4.html http://wiki.linux-nfs.org/index.php/Nfsv4_configuration (ok can't trust that one as they trust the 1st one :D) http://www.vanemery.com/Linux/NFSv4/NFSv4-no-rpcsec.html#notes (fedora implemntation see notes #7) a thread at lkml.org showing they use also /proc/fs/nfsd http://lkml.org/lkml/1998/10/29/114 end with the example, but google also show that ubuntu & suse use also /proc/fs/nfsd btw i have found http://www.penguin-soft.com/penguin/man/7/nfsd.html, here they say we can use /proc/fs/nfs OR /proc/fs/nfsd, anyway even if it's legal to use /proc/fs/nfs as we do, i think it will be safer to use /proc/fs/nfsd instead
historically it has been mounted at /proc/fs/nfs, but /proc/fs/nfsd is the new preferred location fixed in cvs
