The Arch installation tutorial I followed originally advised using LVM to have separate root and user logical volumes. However, after some time my root volume started getting full, so I figured I would take 10GB off of my home volume and add it to the root one. Simple, right?
It turns out that lvreduce --size 10G volgroup0/lv_home
doesn’t reduce the size by 10GB, it sets the absolute size to 10GB, and since I had way more than 10GB in that volume, it corrupted my entire system.
There was a warning message, but it seems my past years of Windows use still have me trained to reflexively ignore dire warnings, and so I did it anyway.
Since then I have learned enough to know that I really don’t do anything with LVM, nor do I see much benefit to separate root/home partitions for desktop Linux use, so I reinstalled my system without LVM the next time around. This is, to date, the first and only time I have irreparably broken my Linux install.
As others have mentioned, secondhand laptops and surplus business laptops are very affordable and probably better value for the money than a chromebook. My understanding is that drivers for things like fingerprint sensors, SD card readers, or oddball Wi-Fi chipsets can be issues to watch out for. But personally I don’t care about the fingerprint sensor and only the Wi-Fi would be a major issue to me.
A couple years ago now I picked up a used Acer Swift with 8th gen intel and a dent in the back lid for something like $200 to use as my “throw in a backpack for travel” laptop, and it has been working great. In retrospect, I would have looked for something with 16GB of RAM or upgradeable RAM (8GB soldered to the motherboard, ugh), but aside from that minor gripe it has been a good experience.
