nfsmount.conf - Configuration file for NFS mounts
.SH SYNOPSIS
Configuration file for NFS mounts that allows options
to be set globally, per server or per mount point.

Sections are broken up into three basic categories:
Global options, Server options and Mount Point options.

Multiple changes including: - using \[dq] for double quotes rather than \(lq and \(rq. In almost every case, a regular ASCII double quote is being referred to, so that is what we should use. - clean up indenting in examples. - be explicit about case-insensitive matching. - give more details about permitted options, including the need to use =true and =false for flags - explain Backgroud, Forground and Sloppy - remain trailing white space Signed-off-by: NeilBrown <neilb@suse.de> --- utils/mount/nfsmount.conf.man | 110 ++++++++++++++++++++++++++--------------- 1 file changed, 70 insertions(+), 40 deletions(-)
