Question about /proc/acpi (Debian 7.2 w/ 3.2.0-4-686-pae kernel)
Hi everyone,
I am running Debian Wheezy 7.2 with a 3.2.0-4-686-pae kernel. There are a couple of virtual files and directories in /proc I can't seem to find much information about. I am aware that some of them might be legacy, though. Anyway, here they are:
- acpi: according to this link, this has been deprecated (if so, what has it been replaced with?), but it's still showing up in a pretty new system with a relatively new kernel.
- buddyinfo: this link offers a pretty good explanation, whereas this other link states that this file is used primarily for diagnosing memory fragmentation issues but does not explain how to detect an issue and / or correct it.
Actually there is a bunch of other files / directories, of which I presume the most important ones are:
- cpuinfo
- filesystems
- interrupts
- iomem
- ioports
- modules
- pagetypeinfo
- uptime
- tty
In your opinion, am I missing anything?
As a final note, this is in preparation for Exam 101 in LPIC-1.
Any hints or suggestions will be more than welcome.
Thanks in advance.

systune
SYSTUNE(8) Debian GNU/Linux SYSTUNE(8)
NAME
systune - Kernel tuning through the /proc filesystem.
SYNOPSIS
systune [ -c, --config configfile ] [ -h, --help ] [ -v, --verbose ]
DESCRIPTION
This program writes kernel parameters, previously saved in a configuration file, to the /proc filesystem. This enables kernel performance
to be adjusted without recompiling the kernel.
OPTIONS
-c, --config configfile
Specify an alternative config file. The default is /etc/systune.conf
-h, --help
Print a short explanation of syntax to standard output.
-v, --verbose
Verbose mode: cause non-existent paths in the configuration to generate error output to standard error. Without this option, erro-
neous paths are discarded silently.
CONFIGURATION FILE FORMAT
Each definition takes a single line, in the form path:definition, where path must begin with /proc/sys/. Paths beginning with any other
sequence are silently ignored.
Comments are introduced by the character #. The whole line from the # character onwards is discarded, together with any whitespace immedi-
ately preceding it.
Blank lines are ignored.
FILES
/etc/systune.conf
A file with saved kernel parameters. It is possible to generate this file with the systunedump (8) command.
SEE ALSO
systunedump(8).
