I've self-hosted a wiki for some years now where I keep most of my notes on how to configure things. I reinstall operating systems frequently, and instead of relying on config file backups, I wanted to be able to reproduce the configurations quickly, and be able to adapt them easily for different systems. I like one-liners, and with the servers I've hosted on Linux, I like automated daily updates and have systemd scripts for those. I apparently have over 200 pages of notes, but here's links to the operating systems I use the the most: Windows Fedora Workstation Ubuntu If anyone has any feedback, I'd like to hear it!
As promised, I took coffee time and used to read (scan) through all that info. First of all, many thanks for sharing your Docuwiki with us. Such well organised, wealthy documentation is a delight to see. Hats off to you sir! Now, on the server side both Fedora and Ubuntu a hardening guide, tips can be added and currently missing. Useful hardening software On the installation part on both, using BTFRs or ZFS file system. Some useful apps for both Fedora /Ubuntu Timeshift- snapshot and easy recovery to desired snapshot. Stacer - CC cleaner (to say so) for Linux Lutris - gaming platform deals with Wine ,games installations from Steam, GoG, Humble ,etc. Just some that I remember now, later I could share some more. Audio tweaks can be added, Pulse audio or Pipewire.
I ran through your notes for windows and ubuntu. I assume those guides are your personal tweaks and setup ? I like to point out that the link to LTSB download is gone and on the ubuntu side, providing links to useful programs would be nice. Still need more efforts in order for this guides to be useful for the crowds. Anyway thumbs up for hosting your tweaks/guides.
