ZFS can not go into the linux kernel source tree, as it conflicts with the GPL. Hence, the linux version of ZFS called ZoL (ZFS-On-Linux) must be compiled as kernel module and recompiled at every kernel bump. On normal machines, that's a bit cumbersome, but for Yocto this shouldn't be a problem at all. > > So, given the large fanbase ZFS has, I'm wondering why there are no recipes around? > I'm guessing that ZFS is not really popular on embedded systems ;) > I googled a bit, and these are the only meaningful results I found: > * https://lists.yoctoproject.org/g/yocto/message/29331 > * https://gist.github.com/cveilleux/54961ccc41071e8aee8c19b69fcba78f > > Regards, > Manuel > > > -- Alexandre Belloni, co-owner and COO, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
