I sometimes use a machine at another location with an older 6.8 lts series kernel installed. While reading a bit on the F2FS filesystem. https://wiki.archlinux.org/title/F2FS Warning: The data contained on F2FS partitions can become unusable if the kernel version on the running machine is older than the kernel version used to create the partition. For example, this limitation can manifest if the F2FS partition was created on a mainline kernel provided by linux yet the system has a need to downgrade to an older series of kernels provided by linux-lts. See FS#69363. - This situation could arise using a F2FS usb between a Tumbleweed system and the latter? - Can you give anymore insight on F2FS at all? I understand there is plenty to read on my end about it. I went through the wiki page on it. -Greatest Hopes
