The fstab entry may contain comment/application-specific options, like for example x-systemd.automount or x-initrd.mount. With the recent switch to libmount, the mount options during remount are now gathered via mnt_fs_get_options(), which returns the merged fstab options with the effective options in mountinfo. Unfortunately if one of these application-specific options are set in fstab, the remount will fail with -EINVAL. In systemd 238: Remounting '/test-x-initrd-mount' read-only in with options 'errors=continue,user_xattr,acl'. In systemd 239: Remounting '/test-x-initrd-mount' read-only in with options 'errors=continue,user_xattr,acl,x-initrd.mount'. Failed to remount '/test-x-initrd-mount' read-only: Invalid argument So instead of using mnt_fs_get_options(), we're now using both mnt_fs_get_fs_options() and mnt_fs_get_vfs_options() and merging the results together so we don't get any non-relevant options from fstab.
