- The name of the project. It is commonly used as shorthand for the current Parabola operating system.
- Parabola GNU/Linux
- The former Parabola operating system; used a patched version of the "Linux" kernel.
- Parabola GNU/Linux-libre
- The current Parabola operating system; uses the "Linux-libre" kernel (a fully-libre fork of Linux that is maintained under official GNU auspices).
- Arch Linux
- The operating system that Parabola GNU/Linux-libre is a derivative of. The name is a misnomer; it is a GNU/Linux distribution, but lacks GNU in the name. Not to be rendered as "ArchLinux"; there's a space in there.
- Acceptable shorthand for "Arch Linux".
- (GNU) FSDG
- The (GNU) Free System Distribution Guidelines is the set of guidelines that Parabola follows.
- Debian Free Software Guidelines, the set of guidelines that Debian follows. It is mostly equivalent, but is neither a superset nor a subset of the FSDG.
- "X-libre" is a fork of "X" created for the purpose of complying with FSDG. Some packages with this kind of name are created by the Parabola project (such as "winetricks-libre"), but some (such as "Linux-libre") are maintained by others. See also: Creating -libre packages.
- "X-dfsg" is a fork of "X" created for the purpose of complying with DFSG; these packages are developed/maintained by the Debian project. For example, isdnutils-dfsg is Debian's fork of isdnutils (known to Arch Linux users as "isdn4k-utils"). Because of the similarity between FSDG and DFSG, it also addresses Parabola's policy problems with isdnutils.1
