How to mount disk for non-root accounts?

I have a USB disk on a little NAS controller (NSLU2 running unslung 6.8) that I can access nicely with root with

mount -t cifs \\\\10.134.23.23\\DISK\ 2 /mnt/LKGD7F73A

However, when I run emacs from an user mode xterm prompt, emacs cannot read and write the files on /mnt/LKGD7F73A. Emacs can see the file but it says the file is not readable.

However, if I start emacs from a root console mode prompt, it can read and write the files.

I did a google search and read that I need to do a "umount /mnt/LKGD7F73A; chmod 777 /LKGD7F73A " and remount but this did not work.

How do I do this? Is there a procedure that will work for fd0 and other devices?

What can I put in fstab so /mnt/LKGD7F73A will automount?

In addition, what command can I use from the bash prompt (running as root) so other uses can access the mounted disk?

Thanks,
Siegfried

LEARN ABOUT V7

switch_root

SWITCH_ROOT(8)						       System Administration						    SWITCH_ROOT(8)

NAME

       switch_root - switch to another filesystem as the root of the mount tree

SYNOPSIS

       switch_root [-hV]

       switch_root newroot init [arg...]

DESCRIPTION

       switch_root moves already mounted /proc, /dev, /sys and /run to newroot and makes newroot the new root filesystem and starts init process.

       WARNING: switch_root removes recursively all files and directories on the current root filesystem.

OPTIONS

       -h, --help
	      Display help text and exit.

       -V, --version
	      Display version information and exit.

RETURN VALUE

       switch_root returns 0 on success and 1 on failure.

NOTES

       switch_root  will  fail	to  function if newroot is not the root of a mount. If you want to switch root into a directory that does not meet
       this requirement then you can first use a bind-mounting trick to turn any directory into a mount point:

	      mount --bind $DIR $DIR

       chroot(2), init(8), mkinitrd(8), mount(8)
