FreeBSD provides binary compatibility with Linux®, allowing users to install and run most Linux® binaries on a FreeBSD system without having to first modify the binary. It has even been reported that, in some situations, Linux® binaries perform better on FreeBSD than they do on Linux®.
However, some Linux®-specific operating system features are not supported under FreeBSD. For example, Linux® binaries will not work on FreeBSD if they overly use i386™ specific calls, such as enabling virtual 8086 mode.
Support for 64-bit binary compatibility with Linux® was added in FreeBSD 10.3.
