The entire system can be compiled in minutes, and uses up up only a couple hundred megabytes of disk space (despite being statically linked). It is entirely C-based, and most packages make limited use of GNU C extensions. Additionally all packages are built in a way that ensures the binaries are 100% reproducible.

Updating your system is as simple as

git -C /src/oasis pull
samu -C /src/oasis commit
doas git -C / merge

For more information, see the wiki.

Principles

Binaries should be linked statically. This is made possible by lightweight system components like musl libc, and a central source repository to keep track of system-wide dependencies.
Software components should be built in a way that allows the user to easily customize and/or modify as needed.
Sources can be referenced through a URL or git submodule, but not included directly in the oasis repository. This way, users only need to download the sources they are interested in.
/etc directory should be simple enough for system administrators to understand in its entirety and customize appropriately.

Components

oasis uses software from a lot of different packages. The core system is built up from the following:

musl (libc)
suckless
- sbase, ubase, sinit, sdhcp
openbsd
- pax, fmt, diff, patch, doas
awk
byacc
bzip2
bc
curl
e2fsprogs
git
iproute2
kbd
libressl
lua
mandoc
samurai (ninja-compatible build tool)
openntpd
openssh
perp (process supervisor)
pigz (gzip)
rc
tz
util-linux (fdisk, losetup)
xz
