This is the command mount.posixovl that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
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.
