LSB compliance might be certified for a product by a certification procedure. [ 1 ] LSB specified standard libraries (centered around the ld-lsb.so ), a number of commands and utilities that extend the POSIX standard, the layout of the file system hierarchy , run levels , the printing system, including spoolers such as CUPS and tools like ...
It enables full POSIX compliance for certain Microsoft Windows products. [ citation needed ] Windows Subsystem for Linux , also known as WSL, is a compatibility layer for running Linux binary executables natively on Windows 10 and 11 using a Linux image such as Ubuntu, Debian, or OpenSUSE among others, acting as an upgrade and replacement for ...
The intent of the higher levels is to provide higher confidence that the system's principal security features are reliably implemented. The EAL level does not measure the security of the system itself, it simply states at what level the system was tested. To achieve a particular EAL, the computer system must meet specific assurance requirements ...

Sometimes, SUS compliance can be improved by installing additional packages, but very few Linux systems can be configured to be completely conformant. The Linux Standard Base was formed in 2001 as an attempt to standardize the internal structures of Linux-based systems for increased compatibility. It is based on the POSIX specifications, the ...
In late 2007, BusyBox developers and the Software Freedom Law Center embarked upon a program to gain GPL compliance from distributors of BusyBox in embedded systems, suing those who would not comply. These were claimed to be the first US uses of courts for enforcement of GPL obligations. (See BusyBox GPL lawsuits.)
Modern Linux distributions include a /sys directory as a virtual filesystem (sysfs, comparable to /proc, which is a procfs), which stores and allows modification of the devices connected to the system, [20] whereas many traditional Unix-like operating systems use /sys as a symbolic link to the kernel source tree.
TOMOYO Linux is a lightweight MAC implementation for Linux and Embedded Linux, developed by NTT Data Corporation. It has been merged in Linux Kernel mainline version 2.6.30 in June 2009. [ 16 ] Differently from the label-based approach used by SELinux , TOMOYO Linux performs a pathname-based Mandatory Access Control, separating security domains ...
