-Is it favorable of rather a hindrance to be compatible to POSIX and similar
-standards?
-
-A lot of things in POSIX et al. are designed for [[UNIX]]-like systems with
-traditional monolithic [[kernel]]s.
-
-Thus, a [[microkernel]]-based system, as ours is, has to employ a bunch of
-detours, for example to implement the [[`fork` system call|glibc/fork]].
-
-On the other hand, (mostly) complying to these standards, made a really big
-body of software *just work* without any (or just trivial) [[hurd/porting]].
-Especially so for command-line programs, and libraries.
-
-But: a large part of today's user programs are not written according to POSIX
-et al. low-level interfaces, but against GNOME, GTK+2, and other high-level
-frameworks and libraries. It may be a valid option to enrich these instead of
-striving for total POSIX compliance -- and the high-level programs (that is,
-their users) may not even notice this, but we would avoid a lot of overhead
-that comes with wrapping the [[Hurd interfaces|hurd/interface]] to be POSIX
-compliant.
