Comment 10 for bug 1875577

Hi Richard and Dider, thanks - I have set up encrypted swap on mdraid1 instead. It works but is subject to the same cycle issue - sometimes swap doesn't load, sometimes the boot zfs pool won't mount.

I went to apply the patch, but my system doesn't seem to have the two files that are referenced,
etc/systemd/system-generators/zfs-mount-generator.in
and
/etc/systemd/system/zfs-mount.service.in
and so the patch command failed.

I have probably misunderstood something, sorry... I'm way out of my depth here. FWIW here are the contents of the directories for the missing files:

(system-generators is missing)

drwxr-xr-x 2 root root 3 Apr 27 18:05 zfs-volumes.target.wants

(zfs-mount.service.in is missing)

The system was installed with debootstrap:

dpkg --install debootstrap_1.0.118ubuntu1_all.deb
debootstrap --arch=amd64 focal /mnt http://archive.ubuntu.com/ubuntu/

I did not install any zfs packages separately - the system only has what debootstrap gave it:

root@eu1 ~ dpkg -l | grep zfs
ii libzfs2linux 0.8.3-1ubuntu12 amd64 OpenZFS filesystem library for Linux
ii zfs-initramfs 0.8.3-1ubuntu12 amd64 OpenZFS root filesystem capabilities for Linux - initramfs
ii zfs-zed 0.8.3-1ubuntu12 amd64 OpenZFS Event Daemon
ii zfsutils-linux 0.8.3-1ubuntu12 amd64 command-line tools to manage OpenZFS filesystems

Many thanks for looking at this so quickly! :-)
