Unable to boot after last update

[cscs]

Sorry, I am the wrong one to ask about backups.
Though, I would guess that should work if available.

Other thoughts …
There are a few packages that might work for you: dotpac in the AUR … or maybe etc-update in the repos. But I have used neither.

Third-party utilities

A few third-party utilities providing various levels of automation for these tasks are available:

• dotpac — Basic interactive script with ncurses-based text interface and helpful walkthrough. No merging or auto-merging features.

GitHub - AladW/dotpac || dotpacAUR

• etc-update — Gentoo’s utility, compatible with other distributions including Arch. It provides a simple CLI to view, merge and interactively edit changes. Trivial changes, such as comments, can be merged automatically.

PS. I found this reply that seems to have an idea about using git with pacnews…

Viewing all commits at git for a file (pacnew)

no ! pacman no write in home, and you can run pacman -Fx "bashrc" if you want changes of your .pacnew, you can create your git repo: create repo mkdir ~/.local/share/pacnew.git/ cd ~/.local/share/pacnew.git/; git init #git push # in private repo if you want web diff after all update, before merge, save change in local repo cd ~/.local/share/pacnew.git/ cp -f $(find /etc -name "*.pacnew") ~/.local/share/pacnew.git/ git add -A git commit -am "$(date) pacman update" git push # in priv…

And yet another snippet from the fellow who wrote the merge feature in pacdiff:

MERGEPROG='git merge-file -p --diff3' pacdiff -s

But I honestly have no idea about that - I never use merge.
