will default to checking filesystems in

If an options specifier is present, then only filesystems which contain

will be checked. If the options specifier is prefixed by a negation
operator, then only

.SH SYNOPSIS

+.I /etc/fstab
.SH DESCRIPTION
The file
.B fstab
.SH DESCRIPTION
All files accessible in a Unix system are arranged in one big
tree, the file hierarchy, rooted at
-.BR / .
+.IR / .
These files can be spread out over several devices. The
.B mount
command serves to attach the filesystem found on some device
to verify that the UUIDs are really unique in your system.
The recommended setup is to use tags (e.g.\& \fBLABEL=\fIlabel\fR) rather than
-.B /dev/disk/by-{label,uuid,partuuid,partlabel}
-udev symlinks in the /etc/fstab file. Tags are
+.I /dev/disk/by-{label,uuid,partuuid,partlabel}
+udev symlinks in the
+.I /etc/fstab
+file. Tags are
more readable, robust and portable. The
.BR mount (8)
command internally uses udev
not vice versa. A private mount carries no propagation abilities. An
unbindable mount is a private mount which cannot be cloned through a bind
operation. The detailed semantics are documented in
-.B Documentation/filesystems/sharedsubtree.txt
+.I Documentation/filesystems/sharedsubtree.txt
file in the kernel source tree.
Supported operations are:
The
.B readprofile
command uses the
-.B /proc/profile
+.I /proc/profile
information to print ascii data on standard output. The output is
organized in three columns: the first is the number of clock ticks,
the second is the name of the C function in the kernel where those

Specify a mapfile, which by default is
-.BR /usr/src/linux/System.map .
+.IR /usr/src/linux/System.map .
You should specify the map file on cmdline if your current kernel
isn't the last one you compiled, or if you keep System.map elsewhere.
If the name of the map file ends with `.gz' it is decompressed on the
.TP
\fB\-p\fR, \fB\-\-profile\fR \fIpro-file\fR
Specify a different profiling buffer, which by default is
-.B /proc/profile.
+.IR /proc/profile .
Using a different pro-file is useful if you want to `freeze' the
kernel profiling at some time and read it later. The
-.B /proc/profile
+.I /proc/profile
file can be copied using `cat' or `cp'. There is no more support for
compressed profile buffers, like in
.B readprofile-1.1,
\fB\-r\fR, \fB\-\-reset\fR
Reset the profiling buffer. This can only be invoked by root,
because
-.B /proc/profile
+.I /proc/profile
is readable by everybody but writable only by the superuser.
However, you can make
