.Os
.Sh NAME
.Nm rawnix
.Nd what rawnix is, and what it is not
.Sh DESCRIPTION
rawnix is a source-based Linux system built around musl, Clang/LLVM,
LibreSSL and runit.
There is no glibc, no systemd, no OpenSSL and no X server.
Packages are built from recipes with
.Xr mkpkg 8
and installed with
.Xr pkg 8 ,
and the whole system is meant to be read: every tool is small enough to
follow, and the configuration is files you edit.
.Pp
What follows is the shape of the system.
To install it, see
.Xr installation 7 ;
for what to do afterwards, see
.Xr post-install 7 .
.Ss UEFI, and BIOS where there is no choice
rawnix boots with Limine from a FAT partition mounted at
.Pa /boot/efi ,
and
.Xr limine-sync 8
writes the boot menu there.
UEFI is the path everything is built for: the firmware loads
.Pa EFI/BOOT/BOOTX64.EFI
itself, and the shipped image needs nothing else.
Which one a machine offers is one command:
.Dl $ ls /sys/firmware/efi
On a UEFI system that directory exists.
.Pp
Legacy BIOS works as well, for the machines that give no choice:
a Hetzner Cloud server, qemu without OVMF.
The limine port is built with
.Fl -enable-bios
and
.Fl -enable-bios-cd ,
and
.Ic mkinstall.sh --bios
writes an image that SeaBIOS can boot: a 1 MiB BIOS boot partition
ahead of the ESP, with
.Pa limine-bios.sys
and a
.Pa limine.conf
on the FAT partition and Limine's stage 1 in the image.
Under UEFI that
.Pa limine.conf
is never read.
.Pp
On a BIOS target the bootloader is finished by hand, in the chroot:
.Bd -literal -offset indent
# limine bios-install /dev/sdX 1
# cp /usr/share/limine/limine-bios.sys /boot/efi/
# vi /etc/limine-sync.conf	# console=tty0 console=ttyS0,115200
# limine-sync
.Ed
.Pp
.Xr limine-sync 8
prunes only the files it manages, so the copied
.Pa limine-bios.sys
survives every later run.
After upgrading limine, redo the install and the copy together: stage 1
on the disk and
.Pa limine-bios.sys
on the partition have to come from the same version.
.Ss Wayland, with sway and labwc
There is no X server in the ports tree.
The compositors are
.Xr sway 1
and
.Xr labwc 1 ,
both on wlroots, and the terminal is
.Xr foot 1 .
X11 applications run under
.Li xwayland
if the compositor is built with it.
.Pp
The X11 stack was retired when rawnix moved to Wayland.
The ports still exist, unmaintained, and can be fetched from
.Lk https://git.rawnix.org/attic/xorg/ :
the libraries, the server, the input and video drivers, and the small
utilities that go with them.
They are kept as a reference, not as a supported path: nothing in the
live tree depends on them, and they are not built for the binary
repository.
.Ss runit, with services in /service
Process supervision is runit, in its original layout.
A service is a directory holding a
.Pa run
script, and a service is enabled by linking it into
.Pa /service :
.Bd -literal -offset indent
# ln -s /etc/sv/nginx /service/nginx      # enable
# rm /service/nginx                       # disable
# sv status /service/*                    # what is running
# sv restart nginx                        # restart one
.Ed
.Pp
.Pa /service
is a real directory on the root file system, not
.Pa /var/service ,
not
.Pa /run/runit/service ,
and not a symbolic link to either.
Documentation written for other distributions often says otherwise;
on rawnix the path is the one above.
.Pp
A package that ships a service declares it in its recipe, and
.Xr addpkg 8
makes the link at install time, so a newly installed daemon starts by
itself.
.Ss musl, and what follows from it
The C library is musl.
Glibc-only interfaces are absent, so some software needs patching, and
some needs the small compatibility ports
.Li musl-fts ,
.Li argp-standalone
and
.Li libucontext .
Binaries from other distributions do not run: they ask for
.Pa /lib/ld-linux-x86-64.so.2 ,
which does not exist here.
.Pp
There is no
.Li ldd ;
.Xr revdep 8
reports what is missing instead, reading the package database rather
than running the program.
.Ss Clang and LLVM
Everything is built with clang, and the LLVM package is the toolchain:
compiler, linker
.Pq Li lld ,
C++ library
.Pq Li libc++ ,
and the usual tools.
There is no GCC;
.Li gcc-compat
exists only for configure scripts that insist on the name.
.Pp
LLVM is built for the targets a desktop needs and no more:
.Bd -literal -offset indent
-DLLVM_TARGETS_TO_BUILD="X86;AMDGPU"
.Ed
.Pp
.Li X86
is the machine itself.
.Li AMDGPU
is there for Mesa's shader compiler on AMD graphics, and for ROCm.
On a machine with other graphics, change it:
.Bl -tag -width "nouveau (NVIDIA)"
.It AMD
.Li "X86;AMDGPU" ,
the default.
.It Intel
.Li X86
alone: Mesa's Intel drivers use their own compiler and need no LLVM
target.
.It NVIDIA
.Li "X86;NVPTX"
for nouveau, whose Gallium driver can use it.
.It a virtual machine
.Li X86
alone.
.El
.Pp
Leaving out AMDGPU makes the package markedly smaller and the build
markedly shorter; adding a target you do not have costs both for
nothing.
The setting is in the llvm port's
.Pa MAKEPKG ;
changing it means rebuilding llvm and then Mesa.
.Ss A monolithic kernel, with two exceptions
The kernel is built with everything a machine needs to boot, mount its
disks and reach the network compiled in, not as modules: no initramfs
guesswork, nothing to load before the root file system appears.
.Pp
Two kinds of driver are modules, because which one is needed cannot be
known when the kernel is built: wireless and graphics.
They are loaded at boot from
.Pa /etc/rc.modules ;
see
.Xr post-install 7 ,
.Sx KERNEL MODULES .
.Ss Signed ports, and a binary repository
Every port is signed with
.Xr signify 1 ,
and
.Xr mkpkg 8
verifies the signature against a key in
.Pa /etc/ports/keys/
before it builds anything.
.Xr bulk 8
fetches prebuilt packages for the same ports, so a machine without a
compiler can still be kept up to date; see
.Xr pkg 8
.Fl b .
.Ss The tools
.Bl -tag -width "mkpkg(8)" -compact
.It Xr mkpkg 8
builds a package from a
.Xr MAKEPKG 5
recipe
.It Xr pkg 8
installs, upgrades and removes, with dependencies
.It Xr addpkg 8 , Xr delpkg 8 , Xr infopkg 8
the package database itself
.It Xr ports 8
syncs the ports tree
.It Xr bulk 8
fetches prebuilt packages
.It Xr revdep 8
finds broken library dependencies
.It Xr stik 8
mounts removable devices as an ordinary user
