|
anacron
|
Anacron is a periodic command
scheduler. It executes commands at
intervals specified in days. Unlike cron, it does not assume that the
system is running continuously.
Every time Anacron is run, it reads a configuration file that
specifies the jobs Anacron controls, and their periods in days. If a
job wasn't executed in the last n days, where n is the period of that
job, Anacron executes it. Anacron then records the date in a special
timestamp file that it keeps for each job, so it can know when to run
it again
|
apmd
|

the hardware for block devices using the /proc directory.
It finds partitions on harddisks via fdisk and tries to detect the
filesystems.

messagebus
|
D-BUS is first a library

|
microcode_ctl
|
It decodes and sends new
microcode to the kernel driver to be uploaded to
Intel IA32 processors. (Pentium Pro, PII, PIII, Pentium 4, Celeron,
Xeon etc -
all P6 and above, which does NOT include pentium classics)
It signals the kernel driver to release any buffers it may hold.
The microcode update is volatile and needs to be uploaded on each
system
boot i.e. it doesn't reflash your cpu permanently, reboot and it
reverts
back to the old microcode.
This driver is designed for Intel IA32 microprocessors only, it will
not work
with AMD or any other non-Intel processors as they don't support
microcode
updates or they support it in a manner different from Intel's specs.

checksums from the page cache (the Linux file data cache) directly to
the network, avoiding extra data copies.
