last year when I went back to Arch from Manjaro, I made a critical error. I’m not sure if I was just tired when partitioning things off or what. but I made my root only 20GB instead of the 50 that I had intended. I know in a lot use cases that’ll be fine, but in mine, not so much. with steam compat taking up 1-2gb and keeping one version of pacman cache, I’m constantly getting the redline warning.
Tonight I plan on booting to live and resize my luks drive and hopefully not fuck it. and if I do? oh well…Timeshift will hopefully save me.
I did something similar. I loaded an older version of Mint off a live CD to use GPartEd to resize them. It worked like a charm, no problems.
