Upgrade failure due to missing leapp/dnf-plugin-data.txt

[Rezney]

@bxue Thanks for reporting this issue. We will move this to "leapp-repository" as it is related to upgrades.

I took a look at the machine and the issue seems to be related to the fact that there is "/var" filesystem on separate partition:

Filesystem                 Size  Used Avail Use% Mounted on
/dev/mapper/vg0-lvroot     4.8G  1.1G  3.5G  25% /
devtmpfs                   1.2G     0  1.2G   0% /dev
tmpfs                      1.2G     0  1.2G   0% /dev/shm
tmpfs                      1.2G  8.6M  1.2G   1% /run
tmpfs                      1.2G     0  1.2G   0% /sys/fs/cgroup
/dev/vda1                  248M  115M  121M  49% /boot
/dev/mapper/vg0-lvhome     481M  2.3M  449M   1% /home
/dev/mapper/vg0-lvvar      3.9G  952M  2.8G  26% /var

And when in overlayfs container we see only:

[root@merged ~]# ls -la /var/lib/
total 20
drwxr-xr-x  4 root root 4096 Feb 21 17:16 .
drwxr-xr-x. 1 root root 4096 Feb 21 17:16 ..
drwxr-xr-x  5 root root 4096 Feb 21 17:16 rhsm
drwxr-xr-x  2 root root 4096 Feb 21 17:16 rpm

thus "dnf-plugin-data.txt" file cannot be created as it does not have whole path prepared. We will have to investigate this further.

@pirat89 @shaded-enmity @vinzenz any ideas?

[Rezney]

@pirat89 found that we could use list of directories for lower:

https://wiki.archlinux.org/index.php/Overlay_filesystem

But it looks like those directories are then "merged" together as one lower dir.

@Rezney yep, we will need to do that in different way.
