I might want to keep the /home separate in case I want to install another distro or this one (for some unforeseen reason) break. Then at least the actual data is safe and I can confidently just reinstall the OS.

| Jun 18, 2022 at 7:31 | comment | added | harrymc | The 3 partitions on the disk total 32GB of free space, so you could unify all three to have that much free space. In addition, the swap space might be too large if you never run out of RAM space. For example, this article recommends for RAM of 8GB–64GB the amount of 4G to 0.5X RAM, and when using hibernation the amount of 1.5X RAM. | |

Ok, so just to reiterate for safety - I tarball the entire /usr, put it somewhere safe, then delete the partition containing /usr and extend the partition containing / into the now unused/empty space, and finally unpack the tarball into the all new spacious /. Right? I understand your paranoia about cp, tar is indeed safer.

I suggest something like tar cf /home/tmpsave.tar --one-file-system / /usr

I wouldn't use cp to do this; maybe old prejudice from broken historical versions of cp that corrupt permissions, but you don't need to create the files on /home anyway. Instead, use tar (as root) and save the files together as a single tar file and unpack that onto the new merged partition.
