Linuxconf Kernel Configurator Module
Gustavo Niemeyer
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.
11.. IInnttrroodduuccttiioonn
11..11.. MMiissssiinngg ooppttiioonnss
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.
11..22.. DDeeffaauulltt ooppttiioonnss
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.
22.. OOppttiioonnss
Most of these descriptions were extracted from the kernel
documentation.
22..11.. MMaaxx.. ffiillee hhaannddlleess
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.
22..22.. MMaaxx.. iinnooddee hhaannddlleess
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.
22..33.. MMaaxx.. nnuumm.. ccaacchheedd ddiisskk qquuoottaa
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.
22..44.. MMaaxx.. ssuuppeerr bblloocckk hhaannddlleerrss
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.
22..55.. CCttrrll--aalltt--ddeell
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.
22..66.. FFaaiirr SScchheedduulleerr
Fair Scheduler is a kernel option that greatly improves kernel
abilities to handle processes who try to monopolize the processor
time.
