minecore VS grub-btrfs

MineCore! Now, with much easier Slax version: https://github.com/MineCoreLive/minecore

Free opinion (as system creator lol): use MineCore on Moneroocean 😉 https://github.com/MineCoreLive/minecore

I am trying to set up Minecore on bootable USB to try and do some Monero mining on an old laptop. I am able to create the USB and boot in to Tinycore but I can't seem to be able to enable persistence once i'm there.

I strongly suggest trying out the system I created exclusively for mining. You can run directly from a USB drive to test. Link: https://github.com/MineCoreLive/minecore

Basically, you can get a good idea of the performance of each processor (considering having at least 8gb of ram in any scenario to avoid bottlenecks) from the benckmark itself on xmrig.com, and/or by doing a basic search for the processor plus the term "hashrate" on Google. .. But, in order not to lose the habit (lol), I also recommend testing mining with this system: https://github.com/MineCoreLive/minecore (yes, i set it up), from a usb flash drive. Things like hugepages, msr, running as root are already set up. And all in a linux that uses a ridiculously small amount of system resources. It was set up to extract the largest possible hashate from any equipment (only need the processor, memory and internet connection), using MoneroOcean's xmrig and its ability to automatically change the algorithm to the most profitable currency at the moment.

A minimalist one... https://github.com/MineCoreLive/minecore

Afaik the proper solution is to use https://github.com/Antynea/grub-btrfs/blob/master/initramfs/readme.md and/or rollback the root to a snapshot.

In fact I’m pretty knowledgeable around btrfs and snapshot-tools as well. :D I codevelop https://github.com/Antynea/grub-btrfs.

Something I noticed is that the instructions here before step 2 suggest that the files /etc/initcpio/install/grub-btrfs-overlayfs and /etc/initcpio/hooks/grub-btrfs-overlayfs might exist, and they don't for me. Worth noting that I installed through pacman, which may be a reason they don't exist if I'm reading those instructions correctly.

In Debian, I see that there is a custom installer "Spiral Linux" (https://spirallinux.github.io) with non-default settings that achieves the same kind of mechanism using "grub-btrfs" (https://github.com/Antynea/grub-btrfs) in combination with "snapper-rollback" (https://github.com/jrabinow/snapper-rollback) and a BTRFS subvolume layout suggested by the Arch wiki (https://wiki.archlinux.org/index.php/Snapper#Suggested_filesystem_layout).

grub-btrfs

When the issue first arrived (around 01/11/2023, IIRC), I did try posting an "Issue" on the GitHub page for grub-btrfs (located here), & more specifically on Issue #254, however, for whatever reason (at that time) I wasn't able to make a post on that Issue/forum.
