Automount not triggered on ZFS?

[hubick]

Hi,

I'm running Fedora 35 (kernel 5.14.10) where the /home/ dir is on ZFS (2.1.1). I have a NAS that exports several shares via NFS v4, which I've configured in fstab using the x-systemd.automount mechanism (with x-systemd.requires=network-online.target,x-systemd.requires=zfs.target for good measure).

If I set the mount points for my NFS shares to live under /mnt/ (ext4), accessing the folders triggers them to mount automatically and my NAS files are shown. However, if I set the mount point to live under my home directory (on ZFS), accessing the folders does not result in the NFS shares being mounted automatically, nor list files from my NAS. If I manually execute systemctl start home-myaccount-mynas-myshare.mount on one of the NAS share mount files generated from fstab by systemd, the share is mounted correctly under my home dir, and the NAS files are accessible.

I'm wondering if this failure to trigger the automount is a limitation of ZFS on Linux, or likely something else?

Much Thanks!
