Filesystem
Handling
Like
every
traditional
Unix
system,
Linux
makes
use
of
a
system 's
root
filesystem
:
it
is
the
filesystem
that
is
directly
mounted
by
the
kernel
during
the
booting
phase
and
that
holds
the
system
initialization
scripts
and
the
most
essential
system
program.
Other
filesystems
can
be
mounted
either
by
the
initialization
scripts
or
directly
by
the
users on
directories
of
already
mounted
filesystems.
Being
a
tree
of
directories
every
filesystem
has
its
own
root
directory.
The
directory
on
which
a
filesystem
is
mounted
is
called
the
mount
point.
A
mounted
filesystem
is
a
child
of
the
mounted
