I love Debian (sid) but I always forget how utterly useless the livecd is for any sort of recovery/quick shell things. Just put Gentoo on my usb again because that just works, how ironic that might sound
@f0x The chroot utility in the debian livecd has normally worked well for me. I had to fix some issues with my ZFS root setup after upgrading my Proxmox server to Buster last night.
