lofs(7FS) File Systems lofs(7FS)NAME
lofs - loopback virtual file system
SYNOPSIS
#include <sys/param.h>
#include <sys/mount.h>
int mount (const char* dir, const char* virtual, int mflag, lofs, NULL, 0);
DESCRIPTION
The loopback file system device allows new, virtual file systems to be created, which provide access to existing files using alternate
pathnames. Once the virtual file system is created, other file systems can be mounted within it, without affecting the original file sys-
tem. However, file systems which are subsequently mounted onto the original file system are visible to the virtual file system, unless or
until the corresponding mount point in the virtual file system is covered by a file system mounted there.
virtual is the mount point for the virtual file system. dir is the pathname of the existing file system. mflag specifies the mount options;
the MS_DATA bit in mflag must be set. If the MS_RDONLY bit in mflag is not set, accesses to the loop back file system are the same as
for the underlying file system. Otherwise, all accesses in the loopback file system will be read-only. All other mount(2) options are
inherited from the underlying file systems.
A loopback mount of '/' onto /tmp/newroot allows the entire file system hierarchy to appear as if it were duplicated under /tmp/newroot,
including any file systems mounted from remote NFS servers. All files would then be accessible either from a pathname relative to '/' or
from a pathname relative to /tmp/newroot until such time as a file system is mounted in /tmp/newroot, or any of its subdirectories.
Loopback mounts of '/' can be performed in conjunction with the chroot(2) system call, to provide a complete virtual file system to a
process or family of processes.
Recursive traversal of loopback mount points is not allowed. After the loopback mount of /tmp/newroot, the file /tmp/newroot/tmp/newroot
does not contain yet another file system hierarchy; rather, it appears just as /tmp/newroot did before the loopback mount was performed
(for example, as an empty directory).
Examples
lofs file systems are mounted using:
mount -F lofs /tmp /mnt

Loopback mounts must be used with care; the potential for confusing users and applications is enormous. A loopback mount entry in
/etc/vfstab must be placed after the mount points of both directories it depends on. This is most easily accomplished by making the loop-
back mount entry the last in /etc/vfstab.
