 In particular, it may well fail if the kernel was compiled with devfs

 but devfs is not mounted.

+.PP

+It is possible that files 

+.IR /etc/mtab

+and 

+.IR /proc/mounts

+don't match. The first file is based only on the mount command options, but the

+content of the second file also depends on the kernel and others settings (e.g.

+remote NFS server. In particular case the mount command may reports unreliable

+information about a NFS mount point and the /proc/mounts file usually contains

+more reliable information.)

+.PP

+Checking files on NFS filesystem referenced by file descriptors (i.e. the 

+.BR fcntl 

+and 

+.BR ioctl

+families of functions) may lead to inconsistent result due to the lack of

+consistency check in kernel even if noac is used.
