confused how to chroot + have separate home
 

Hi :-)
A beginner, having just come over to Arch a few days ago (after Mint, Neptune, Manjaro). I never needed to chroot when on previous distros. Using a separate home now. I've set up Timeshift, but having a very difficult time trying to find out how to chroot in, at all, but especially if there was the need to get into Timeshift in order to run a restore ... Timeshift backups are on my /home (sda3).

fdisk -l
/dev/sda1 2048 1026047 1024000 500M Linux filesystem
/dev/sda2 1026048 205826047 204800000 97.7G Linux filesystem
/dev/sda3 205826048 1953525134 1747699087 833.4G Linux filesystem

Reading wiki and lots of guides, and just can't see how to do it. Would be very grateful for any advice.

I do not use Timeshift, but if your goal is to chroot then:

mount sda3 first:

Now:
When you are done, type exit to get out of chroot environment

Thanks dc.901. Much appreciate. :-)
