libnbd and fuse: missing /dev/fuse device

[Autumn Jolitz]

Hi,

After installing `ocaml` / `nbdkit` and `go121`, I compiled libnbd and more specifically libnbd/fuse. My goal is to be able to mount an nbd device in user space.

However, a call to `fuse_mount (fuse, mountpoint)` returns -1 with "fuse: failed to open fuse device: No such file or directory”

A kdump shows:

    130283:1    nbdfuse  CALL  open(0x80060b95e,0x2<O_RDWR>,<unused>0)
    130283:1    nbdfuse  NAMI  "/dev/fuse"
    130283:1    nbdfuse  RET   open -1 errno 2 No such file or directory

Okay, so we’re not getting an actual /dev/fuse device despite a successful fuse_new et al. I’ll fess up to knowing quite little about this subsystem.

Would someone be able to give me some advice or pointers?
