What's the relationship between a Linux OS and a kernel?

阅读更多关于 What's the relationship between a Linux OS and a kernel?

问题 I've been using Linux for several years, but never stepped beyond installing from a CD/DVD. If the app manager didn't have what I was looking for in the software, then I was a lost cause. But right now I'm trying to get a grip around what "Linux" is. The first word that pops into my head is "kernel". After reading on Wikipedia, I understand that a kernel is software running to give other software (OS + apps) access to hardware (CPU, RAM+++). It also handles memory, but isn't that what the OS

How can Docker run distros with different kernels?

阅读更多关于 How can Docker run distros with different kernels?

问题 How can docker run on a Debian host maybe an OpenSUSE in a container? It uses different kernel, with separated modules. Also older Debian versions have used older kernels, so how can run it on a kernel version 3.10+ ? Older kernels have only older built in functions, how can an old distro manage new features? What is "the trick" in it? 回答1: How can docker run on a Debian host maybe an OpenSUSE in a container Because the kernel is the same and will support the Docker engine to run all those

How to Debug MIPS elf?

阅读更多关于 How to Debug MIPS elf?

问题 Suppose I have a MIPS elf binary (meaning someone cross compiled/compiled on MIPS a MIPS linux executable) Are there any linux distros that are compiled to run on mips architecture that could perhaps run the executable? I've looked around, but all I can find is linux-mips. Even better would be if the distro was already installed to a VM disk file, and you could just download it. Is there any guaranteed way to run the MIPS elf on a non MIPS distro? Like using some qemu setup or something? (By

Find name of linux distro from java

问题 We are writing a small library in java that needs to collect information from the underlying system. We are able to read most of the stuff from system properties in java, but we cannot seem to find the right way to extract the name of the distro when run on linux. The call System.getProperty("os.name"); return "Linux" (which we also collect) but we are looking for a way to get e.g. "Ubuntu" as well. We need this solution in java and would like to not have to do some /etc/release parsing 回答1:
