From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

So here's my situation:

I'm on Fedora 40 on a laptop and I've recently decided to add a Hibernate option to my own logout/powermenu script that I use. The script executes systemctl hibernate but there's a problem. It didn't seem to work. When I ran the above command in terminal, I got an error stating that there's not enough suitable swap space for that. Turns out that I'm using swap-to-zram hence why Hibernate doesn't work.

So, I decided to ask ChatGPT and it recommended creating a swapfile. I can do that no problem.

The thing is, if I'm using swap-to-zram, I concluded it is likely that if I'm making use of that swap-to-zram all the time, I will probably need a larger swapfile for the hibernation.

So I asked our AI overlords if there's a risk in that. It said there isn't any real risk, other than increased drive wear-and-tear and potential performance issues.

Dear Linux users of Lemmy, are there any issues or concerns I should be aware of before attempting something like this (running multiple types of swap simultaneously, excess swapfile space, etc.)? Thank you.

Edit: Not sure how relevant it is, seeing as I'm not asking about swap partitions, but I'll mention using BTRFS, just in case. And no, I don't know anything about it, I just know it has cool features I'm yet to start learning about.

Can I suggest reading documentation instead of asking LLM's that are routinely known to just make shit up?

https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate says it's possible with a swap file as the backing device but that swap to zram isn't supported. I haven't personally tried it though.

So it IS possible, as I already found out. If the Arch wiki isn't saying things like "doing this can break your system" then it's fine by me.
