<title>Linuxconf Kernel Configurator Module
<author>Gustavo Niemeyer
<abstract>
This dialog allows you to configure many aspects of the linux
kernel. You should be very careful with what you change here,
since a bad option may crash your linux box and require that
you boot as single user to correct your options.
</abstract>
<sect>Introduction
<sect1>Missing options
<p>
Note that maybe some of the options listed here are not available
for you. It depends if your kernel is offering this functionality
or not.
<sect1>Default options
<p>
When you set an option to default, it doesn't mean that as soon
as you get out of linuxconf, this option will return to default
value. Linuxconf has no way to know what are the default options
of your kernel. It means that when you set an option to default,
Linuxconf will not intervent in this option anymore, no matter
what it is set to. Remember that kernel options are usually set
in the /proc file system and, as this file system is mapped in
memory, everything will be reset when you shutdown your machine.
<sect>Options
<p>
Most of these descriptions were extracted from the kernel
documentation.
<sect1>Max. file handles
<p>
This value denotes the maximum number of file handles that the
Linux kernel will allocate. When you get a lot of error messages
about running out of file handles, you might want to raise this
limit.
<sect1>Max. inode handles
<p>
This value denotes the maximum number of inode handlers. This value
should be 3 to 4 times larger than the value in "Max. file handles",
since stdin, stdout, and network sockets also need an inode struct
to handle them. If you regularly run out of inodes, you should
increase this value.
<sect1>Max. num. cached disk quota
<p>
This value denotes the maximum number of cached disk quota entries.
If the number of free cached disk quotas is very low and you have
a large number of simultaneous system users, you might want to
raise the limit.
<sect1>Max. super block handlers
<p>
Every mounted file system needs a super block, so if you plan to
mount lots of file systems, you may want to increase these numbers.
<sect1>Ctrl-alt-del
<p>
When this option is disabled, ctrl-alt-del is trapped and sent
to the ``init'' program to handle a graceful restart. However, when
it is enabled, Linux's reaction to this key combination will be
an immediate reboot, without syncing its dirty buffers.
<sect1>Fair Scheduler
<p>
Fair Scheduler is a kernel option that greatly improves kernel
abilities to handle processes who try to monopolize the processor
time.
