From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

doas
is quite popular in the BSD world, and was ported to Linux a few years ago (via the OpenDoas project).For starters, it's is a lot smaller than sudo - under 2k lines of code vs sudo's 132k - this makes it lot more easier to audit and maintain, and technically less likely to have vulnerabilities.
Another security advantage is that
doas
doesn't pass on the environment variables by default (you'd have to explicitly declare the ones you want to pass, which you can do so in the config).The config is also a lot simpler, and doesn't force you to use
visudo
- which never made sense to me,visudo
should've just generated the actual config, instead of checking it after the fact. Kinda like howgrubby
orgrub2-mkconfig
works. But no need for that complexity with doas.Eg, the most basic
doas
config could just have one line in the file:permit: wheel
. Maybe have another line for programs you want to run without a password, likepermit nopass dexter cmd pacman
.Awesome. Thanks for the insight.
