NAME

posixovl -- FUSE file system that provides POSIX functionality

SYNOPSIS

     mount.posixovl [-F] [-S SOURCE_DIR] TARGET_DIR [-- fuseopts]
 
 

DESCRIPTION

If no source directory is given, the TARGET_DIR specifies both source and target (mount point), yielding an ``over mount''.

Supports: chmod, chown, hardlink, mkfifo, mknod, symlink/readlink ACLs/xattrs (only in passthrough mode, no emulation).

NOTES

Using posixovl on an already POSIX-behaving file system (e.g. XFS) incurs some issues, since detecting whether a path is POSIX behaving or not is difficult. Hence, the following decision was made:
     - permissions will be set to the default permissions (see below) unless
       a HCB is found that can override these
     - all lower-level files will be operated on/created with the user who
       initiated the mount
 
 

If no HCB exists for a file or directory, the default permissions are 644 and 755, respectively. The owner and group of the inode will be the owner/group of the real file.

Each non-regular, non-directory virtual file will have a zero-size real file. Simplifies handling, and makes it apparent the object exists when using other operating system.

Command df(1) will show:

     $ df -Tah
     File System    Type    Size  Used Avail Use% Mounted on
     /dev/hda5     vfat    5.9G  2.1G  3.9G  35% /windows/D
     posix-overlay(/windows/D)
          fuse.posixovl    5.9G  2.1G  3.9G  35% /windows/D
 
 

OPTIONS

-F
Option -F will disable permission and ownership checks that would be required in case you have a POSIX mount over VFAT. For example, where /vfat is vfat, and /vfat/xfs is a POSIX-behaving file system.

EXAMPLES

In general, posixovl does not handle case-insensitivity of the underlying file system (in case of VFAT, for example). If you create a file X0 on VFAT, it is usually lowercased to x0, which may break some software, namely X.org. In order to make VFAT behave more POSIX-like, the following mount options are recommended:
     mount -t vfat /dev/sda5 /mnt/vfat -o check=s,shortname=mixed
 
 

ENVIRONMENT

None.

FILES

None.
