The patch is compiled as usual, but the generated code has additional information about all changed code pieces caused by original source code modification and information on to how to apply these code pieces. The resulting code modifications are safely applied to the running kernel. A special KernelCare kernel module applies the patches. It ...
debconf is a software utility for performing system-wide configuration tasks on Unix-like operating systems. It is developed for the Debian Linux distribution, and is closely integrated with Debian's package management system, dpkg.
A kernel oops often leads to a kernel panic when the system attempts to use resources that have been lost. Some kernels are configured to panic when many oopses (10,000 by default) have occurred. Some kernels are configured to panic when many oopses (10,000 by default) have occurred.
Debian Unstable, known as "Sid", contains all the latest packages as soon as they are available, and follows a rolling-release model. [6]Once a package has been in Debian Unstable for 2–10 days (depending on the urgency of the upload), doesn't introduce critical bugs and doesn't break other packages (among other conditions), it is included in Debian Testing, also known as "next-stable".
Kdump replaced the deprecated Linux Kernel Crash Dumps (LKCD) tool, which also wrote the contents of memory upon a crash. [11] Kdump presents a more efficient, scalable utility than LKCD. [12] kdump functionality, together with kexec, was merged into the Linux kernel mainline in kernel version 2.6.13, which was released on August 29, 2005. [13]
After recompiling a kernel binary image from source code, a kernel panic while booting the resulting kernel is a common problem if the kernel was not correctly configured, compiled or installed. [8] Add-on hardware or malfunctioning RAM could also be sources of fatal kernel errors during start up, due to incompatibility with the OS or a missing ...
As boot time fsck is expected to run without user intervention, it generally defaults to not perform any destructive operations. This may be in the form of a read-only check (failing whenever issues are found), or more commonly, a "preen" -p mode that only fixes innocuous issues commonly found after an unclean shutdown (i.e. crash, power fail).
modprobe is a Linux program originally written by Rusty Russell and used to add a loadable kernel module to the Linux kernel or to remove a loadable kernel module from the kernel. It is commonly used indirectly: udev relies upon modprobe to load drivers for automatically detected hardware.
