Something useful / security here https://wiki.alpinelinux.org/wiki/Alpine_Linux:Overview#Technical_overview ?
Generally, I don’t want to add to deep analysis of (in)security of other Linux distributions. Reasons:
- might get outdated
- distracts developer time from other tasks
- might get disputed and then needs to be debated, fixed
The reason for that wiki page, listing these distribution is to demonstrate that these were considered as base distribution for Whonix before. During the early years of TorBOX / Whonix there were people repeating the myth “Why don’t you build on top of OpenBSD which is the most secure operating system?” Since these things nowadays are documented, easy to find on google and good arguments made, nobody is ever making these suggestions. Asking good questions such as in case of FreeBSD helped to get rid of these suggestive / myths. Looks to me like reading these write-ups people give up on these distributions / suggestions.
Reason to expand these notes would only be if any distribution(s) would be seriously considered porting to.
