What does HackerNews think of doas?

OpenDOAS has actually had the OpenBSD-specific code removed (https://github.com/Duncaen/OpenDoas/commit/74449f015ff7a7230...), and replaces some of the doas mechanisms that rely upon OpenBSD to work with sudo-like flag files and suchlike.

There are, moreover, 2 ports of doas to other systems. OpenDOAS is one. Jesse Smith's https://github.com/slicer69/doas is the other. The latter retains the OpenBSD-specific code, and is the more portable of the two at the expense of only doing everything that the tool is capable of when actually built on OpenBSD.

There's also a straight port of doas:

However unlike sudo and opendoas this does not implement the persist feature on not-OpenBSD.

As mentioned elsewhere, this is because it relies upon a kernel mechanism that Linux simply does not have, and fixing this involves fixing Linux.

To which I add that it is important not to conflate Jesse Smith's doas, the portable doas that has code for different operating systems including OpenBSD, with Duncan Overbruck's OpenDoas, the "open" doas that is tied to Linux has has had the code for other operating systems removed and mechanisms copied in from sudo for things like timeout flag files.

I've heard of doas sometimes and it's much simpler than sudo, but it's powerful. Doas has two non-official port for Linux[0][1], but it would be great if someone developed an official tool like doas for Linux.

If backward compatibility is not required, then OpenBSD's doas[0] may be a suitable alternative. Someone[1]'s ported it to other UNIX-like systems, though I don't know how good the port is.
