The following line:

/path1  /path2  posixovl    none    0   0

fails with the error:

/sbin/mount.posixovl: invalid option -- 'o'

Usage: /sbin/mount.posixovl [-F] [-S source] mountpoint [-- fuseoptions]

This is because mount.posixovl uses a non standard mount syntax, and fstab will call it assuming default mount syntax, eg.

mount.posixovl /path1 /path2 -o [whatsoever_/etc/fstab_options]

EDIT #1:
Same problem, solved with an uglier hack in this linuxquestions.org Q&A titled: [SOLVED] How to get a fuse-posixovl partition mounted at bootup?

I wrote a wrapper for mount.posixovl that enables it to be used with fstab

First, rename /sbin/mount.posixovl to something else, like /sbin/mount.posixovl.orig

Finally, create a new file /sbin/mount.posixovl whith the following contents:

#!/bin/bash

# wrapper for mount.posixovl to conform with common mount syntax

# with this wrapper posixovl can be used in fstab



# location of the original mount.posixovl

origposixovl="/sbin/mount.posixovl.orig"



# gather inputs

while [ $# -gt 0 ]; do

        if [[ "$1" == -* ]]; then

                # var is an input switch

                # we can only use the -o or -F switches

                if [[ "$1" == *F* ]]; then

                        optsF="-F"

                else

                        optsF=""

                fi

                if [[ "$1" == *o* ]]; then

                        shift

                        optsfuse="-- -o $1"

                else

                        optsfuse=""

                fi

                shift

        else

                # var is a main argument

                sourcedir="$1"

                shift

                if [[ "$1" != -* ]]; then

                        targetdir="$1"

                        shift

                else

                        targetdir="$sourcedir"

                fi

        fi

done



# verify inputs

if [ "$sourcedir" == "" ]; then

        echo "no source specified"

        exit 1

fi

if [ "$targetdir" == "" ]; then

        echo "no target specified"

        exit 1

fi



# build mount.posixovl command

"$origposixovl" $optsF -S "$sourcedir" "$targetdir" $optsfuse

Naturally, set the newly created /sbin/mount.posixovl to be executeable (chmod +x /sbin/mount.posixovl)

It is useful mounting posixovl trough fstab
