Apologies to Randall Monroe.
OpenDoas: a portable version of OpenBSD’s
doas is a minimal replacement for the venerable
sudo. It was
initially written by Ted Unangst
of the OpenBSD project to provide 95% of the features of
sudo with a
fraction of the codebase.
This is still a work in progress! Please do not deploy yet in a critical
environment! Of note,
doas semantics may yet change, and I haven’t
performed even a trivial security audit of my additions.
Building and installing
doas should be just a simple
The included makefile also has an installation target. Installation
requires root access to properly set the executable permissions. You’ll
also need to install a
make && sudo make install echo "permit :admin" | sudo tee /etc/doas.conf
Oh the irony, using
sudo to install
About the port
As much as possible I’ve attempted to stick to
doas as tedu desired
it. As things stand it’s essentially just code lifted from OpenBSD with
PAM based authentication glommed on to it.
I’ve used cvsync and git-cvsimport to retain the history of the core source files. I may choose to go back and do the same with some of the compatibility functions (such as reallocarray.c).
I have found it necessary to make some fixes to the codebase. One was a segfault due to differences in yacc/bison, others were just minor fixes to warnings. Once this appears stable, I may try to upstream some of these.
Currently, this is only tested on MacOSX 10.10 with Clang. My next goal is support for Fedora Linux as well. Contributions gladly accepted. ;-)
