Description of problem: If Gnome Software has updates pending, and I reboot from gnome-shell (upper right corner, power button icon, restart) with "Install pending software updates" not checked, an empty file "null" is created in the root directory. Version-Release number of selected component (if applicable): device-mapper-1.02.131-3.fc25.x86_64 How reproducible: Always Steps to Reproduce: 1. Clean install Fedora 25 and reboot 2. Wait for some updates to appear in gnome-software 3. reboot without installing updates Actual results: empty file /null appears; delete the file and restart again from gnome-shell as described and the file reappears Expected results: file should not exist Additional info: chattr +i on /null and reboot, then use 'journalctl -b-1 | grep null' to see if this file is being touched at restart time, and it is: Dec 16 10:19:30 localhost.localdomain blkdeactivate[1787]: /usr/sbin/blkdeactivate: line 469: /null: Operation not permitted
Is not reproducible with device-mapper-1.02.136-1.fc25.x86_64... hmm. Also changing summary because I can reproduce this even without pending updates, just a regular gnome-shell restart is all that was needed to create this null file.
