As an Arch User who keeps hearing about OpenSUSE being a more stable rolling release....mind going into it a bit more? I'm happy on my system, mind, but idk, could be I'm missing out on something big for not making the jump. If nothing else, I'll know my options
To be frank I went away from Gentoo for much the same reason. And the constant compilation. I only used it once after that for a small project where I needed to minimise what actually lands in the OS.
I have multiple devices, but I just use my trusty KNOPPIX LiveCD to unlock the disk and move everything onto an external hard drive before either troubleshooting via chroot or just doing a clean install.
