[Pkg-zfsonlinux-devel] Bug#1110397: zfs-initramfs: zfs initramfs script tries to mount canmount=noauto filesystems

[Wessel Dankers]

Package: zfs-initramfs
Version: 2.3.2-2
Severity: normal

Dear Maintainer,

The current zfs initramfs script (/usr/share/initramfs-tools/scripts/zfs)
skips filesystems with canmount=off but not filesystems with
canmount=noauto.

This is especially annoying with encrypted filesystems on headless systems.

A simple extra check around line 342 should fix this. Or perhaps it
could check for canmount=on and skip mounting for all other values.

Steps to reproduce:

1) zfs create -o canmount=noauto pool/foo
2) reboot
3) error during boot that /root//foo can't be mounted because the directory
   does not exist.
4) mkdir /foo
5) reboot
6) notice how /foo is mounted even though it shouldn't be

Many thanks for the hard work!
