Edward78 In a perfect world yes definitely but Solus works with a small team and limited resources. I don't recall any of the big distros having boot repair features either but maybe I'm wrong on that one.
My own experience with Linux has been that boot seems to be quite resilient to damage due to forced shutdowns and similar, only breaking if I fiddled with it too much.
I remember Windows had it's own system repair features which, from personal experience, involved at least 16 hours of industrious disc activity followed by the simple message "Something went wrong". And that was as good as it got even with the fantastic wealth of Microsoft financing it.
Unless there is massively important data in your home partition it is mostly quicker to wipe and rewrite. I learnt that back in Win 95 days.
A simple bit of advice. Always keep backups on other media. If you do something clever with your OS, write it down and back it up with everything else. That way installing again will be easier.
I use scripts to run updates, install software I want and remove software that I don't. They also set up fstrim timer to run which is very important if you have an SSD. Everything important gets manually saved to external hard drives. This can be a pita but previously I have regretted using backup software as it failed to save all the things I needed it to, or, on one occasion would not let me restore my files to a newly set up PC. Auto backups only get tested when you need them most and that is when they are most likely to fail.
