UNIX*](http://www.informit.com/articles/printerfriendly.aspx?p=691503), an
article by David Chisnall.
- * [*Ghosts of Unix Past: a historical search for design
- patterns*](http://lwn.net/Articles/411845/) (2010-10-27) by Neil Brown,
- including file descriptors and the single, hierarchical namespace.
+ * The first in the series, {{$2010_brown_ghosts_1}} introduces the concepts
+ of [[file_descriptor]]s and the single, hierarchical [[namespace]].
+
+ Next, {{$2010_brown_ghosts_2}} discusses issues with *conflated designs*
+ such as the `mount` command (a problem we have partly solved / solved
+ differently with our [[hurd/translator]] approach and the
+ [[hurd/virtual_file_system]]), and the plethora of flags that can be passed
+ to the `open` [[system_call]].
+
+ In {{$2010_brown_ghosts_3}}, he deals with *unfixable designs*, such as
+ [[UNIX signals|glibc/signals]] and the *UNIX permission model* (which is
+ clearly inferior to a [[capability]]-based system).
* [*UNIX File Permissions*](http://www.greenend.org.uk/rjk/2004/perms.html)
