Do Linux run on Sparc?

Implementations of the SPARC architecture were initially designed and used for workstations, and then used for larger SMP servers produced by Sun Microsystems and Fujitsu, among others. SPARC machines generally use Sun's Solaris Operating System (designed for SPARC), but other operating systems such as NEXTSTEP, RTEMS, FreeBSD, OpenBSD, NetBSD, and Linux are used on SPARC-based systems.
