`mount` command and POSIX Utility Syntax Guidelines

[Timothy Madden <terminatorul@gmail.com>]

Hello,

I have the little annoying problem that I can not mount a DAV folder 
with the davfs2 filesystem, because I usually keep POSIXLY_CORRECT 
environment variable set. The var allows me to keep an "aliases" file 
(similar to ~/.basrc) and change it when needed if I put the file name 
in the ENV variable.

The problem is with the invocation of the mount helper command. `mount` 
will compose a command line like this:
    /sbin/mount.davfs \
           https://storage-file-eu.gmx.com/ \
           ./gmx-file-storage \
           -o rw,nosuid,nodev,noauto,user,_netdev,exec
where the option arguments ("-o rw,...") follow the operands (device, 
mount point) on the command line.

However GNU getopts() (from glibc) follows POSIX Utility Syntax 
Guidelines in this case and expects the option arguments before the 
operands.

Subsequently the mount command returns and error when mounting my DAV
folders. I am currently using a wrapper executable around mount.davfs 
that changes the order of arguments on the command line to make it work.

I hope mount command composes such a command line for historical reasons 
and that there are no hidden problems with the order of the options on 
the command line for mount helpers.

Is it please possible for mount command to be updated to change the 
order of arguments on the command line, so that it follows the POSIX 
guidelines ? At least when POSIXLY_CORRECT is set in the environment ?

I have "mount from util-linux 2.21.2 (with libblkid support)" on 
Slackware 13.37 32-bit updated with Slackware-current packages. Also 
happens on up-to-date CentOS 6.3 64-bit with updates from centosplus 
repository, that is "mount from util-linux-ng 2.17.2 (with libblkid and 
selinux support)".
