Timeshift itself borked my shit up. I had to reinstall all registered packages to fix its fuckups…
sudo aptitude reinstall '~i'
Edit: Sure it took a long while, about as long as a full OS reinstall, but never once was there any issue with the kernel.
I’ve been running different versions of Linux since 2011. My crippled kernel count is still zero to this day.
And that’s even after stripping it of the drivers I’ll never need, stripping it of the languages I’ll never need, and even rerouting all temporary files, internet cache, and even core OS log files to tmpfs and ramfs.
Yeah, try troubleshooting an OS with no log files after reboot. Yeah, I can do that, hella performance boost!
My test of Timeshift was pretty simple and straightforward.
Fresh install Linux Mint
Install most of the main software I wanted.
Do a Timeshift backup.
Install some extra software I didn’t necessarily need, but might want to use someday.
Restore the backup from step 3.
Results: Everything from step 4 was still registered as installed, but almost nothing from step 4 actually worked.
So I brute force reinstalled everything in place, and haven’t used Timeshift since. I’m perfectly comfortable using the terminal, and at worst a live boot media, to fix any issues that might come up.
