@ -12,7 +12,9 @@ The system aims to be an Unix-clone and is heavily based on POSIX. However, I've
drawn much inspiration from systems such as Plan 9, GNU/Hurd and MINIX. Indeed,
I plan to construct a micro-kernel with user-space filesystems, per-process
namespaces, replacing many system calls with filesystem nodes, and other
exciting features.
exciting features. This design will make it safe to let normal users perform
operations such as mounting and create their own "sub-operating-system"
environment where they are the root.

The Sortix kernel has very basic filesystem support. The root filesystem / is
simply a single-directory RAM filesystem. The init ramdisk is mounted read-only
on /bin and various devices are accessable through the /dev filesystem. A lot of
work is currently going into implementing a fully-working kernel virtual file
system able to outsource filesystem requests to user-space servers. Once this is
completed we will be able to shape Sortix into a real microkernel based system.
on /bin and various devices are accessable through the /dev filesystem. Work is
underway to create an ext2 filesystem server, but it won't be of much use until
the kernel virtual filesystem is completed in the 0.7dev development cycle.
Job control and Unix signals is not fully or correctly implemented. This means
that sequences such as Ctrl-C (SIGINT) not always works correctly. This will
be implemented soon enough (depends partially on VFS; see above).
There currently is no concept of users in the system (only the root user
exists). I decided to delay making a multi-user system until the base system is
in place. Note that there is only a single terminal - even though the system is
a multi-process system, there is only a single /dev/vga and there is no
framework in place for sharing it.

To build the Sortix source code you need to install a few dependencies. First of
all you need the GNU Compiler Collection (C and C++), GNU Make, and GNU
Binutils. You then need to build and install the included macro preprocessor
