nxd-fuse is fuse package from those distribution with backported
git.kernel.org/linus/ad2ba64dd489 for wendelin.core 2 to be able to
fully and explicitly control OS pagecache for files that wcfs serves.
This patch is very essential for wendelin.core 2.
The sources for nxd-fuse package are located in fs/fuse/ here:
https://lab.nexedi.com/kirr/linux/commits/nxd/fuse/debian/buster (Debian 10)
https://lab.nexedi.com/kirr/linux/commits/nxd/fuse/debian/stretch (Debian 9)
https://lab.nexedi.com/kirr/linux/commits/nxd/fuse/ubuntu/xenial (Ubuntu 16.04)
I tested the package by myself for a long time on my Debian10-based
laptop via go-fuse tests and while working on wendelin.core. Ubuntu
package was also tested for a long time on my KVM via manually running
the same tests and, recently, via running wendelin.core 2 tests on
testnode located on the same KVM. I tested Debian 9 module only briefly
on my Debian 9 KVM, but given that the diff in between nxd-fuse and
std/ fs/fuse/ for that kernel is essentially only
git.kernel.org/linus/ad2ba64dd489, and that the debianisation was
already tested well via Debian10, and that go-fuse and wendelin.core 2
tests pass, it should be ok.
The packages are built on OBS here:
I've used vifib-kernel role as the place where to add corresponding
play. Nxd-fuse is tightly related to kernel and requires reboot after
installation, which, if I understood correctly, needs infrastructure
internal to that role to work correctly.
