A followup tod7a67402a8For `mount -t zfs -o opts ds mp` command line some implementations of `mount(8)`, e. g. Busybox in Debian work as follows: ``` newfstatat(AT_FDCWD, "ds", 0x7fff826f4ab0, 0) = -1 mount("ds", "mp", "zfs", MS_SILENT, NULL) = 0 ``` The logic above skips completely `mount.zfs` and prevents us from reading filesystem properties and applying mount options. For comparison, the coreutils `mount(8)` implementation does: ``` openat(AT_FDCWD, "/proc/filesystems", O_RDONLY|O_CLOEXEC) = 3 // figure out that zfs is a `nodev` filesystem and look for a helper newfstatat(AT_FDCWD, "/sbin/mount.zfs" ...) = 0 execve("/sbin/mount.zfs" ...) = 0 ``` Using `mount.zfs` in initramfs would help circumvent deficiencies of some of `mount(8)` implementations. `mount -t zfs` translates to `mount.zfs` invocation, except for cases when explicitly disabled by `-i`.
