  • rear version: Relax-and-Recover 1.18 / Git
  • OS version: OS_VENDOR=Fedora
    OS_VERSION=23
  • rear configuration files: OUTPUT=USB
    USB_DEVICE=/dev/disk/by-label/REAR-000
    BACKUP=NETFS
    BACKUP_URL=usb:///dev/disk/by-label/REAR-000
  • Brief description of the issue
    The rear recover failed to restore the lone user of the system. Root account was restored.
    The same rear configuration used to work on Fedora 23 LVM with rear 1.17. I re-installed
    Fedora23 recently and placed / and /home on Btrfs. The rear recover did restore the system.
    I have the login screen with my lone user but could not login with the password. I am able to login
    ROOT account and find the lone user. I reset the password of it and the same problem persisted.
    The home directory was totally empty, which is also empty in the backup file. I spotted no error in
    the backup log but found the errors in recover log:
    2016-06-09 18:48:21 Including restore/default/90_create_missing_directories.sh
    2016-06-09 18:48:21 Restore the Mountpoints (with permissions) from /var/lib/rear/recovery/mountpoint_permissions
    chown: invalid user: 'ryan:ryan'
    chown: invalid user: 'gdm:gdm'
  • Work-around, I do not have any

"/home on Btrfs" means that for usual tools "/home" behaves
as if it was on a separated filesystem because btrfs subvolumes
behave as if there were separated filesystems.

Accordingly you must explicitly specify to backup the content
in "/home".

Cf. the btrfs example configs for SLE in
usr/share/rear/conf/examples/SLE12-btrfs-example.conf
usr/share/rear/conf/examples/SLE12-SP1-btrfs-example.conf

I assume with https://github.com/rear/rear/issues/873#issuecomment-225536867
the issue is sufficiently solved.
If not you can reopen it.
