Description patrick korsnick 2012-04-01 21:32:06 UTC

Description of problem:

Trying to move /tmp to RAM to avoid extra writes to an SSD used as root drive.
Adding this line to /etc/fstab worked for me on f16:

none    /tmp    tmpfs   defaults        0 0

However on f17 adding this line prevents the machine from booting.


Version-Release number of selected component (if applicable):

17

How reproducible:

every boot fails

Steps to Reproduce:
1. add above line to /etc/fstab
2. reboot
3.
  
Actual results:

boot halts 

Expected results:

machine to boot up

Works for me. What exact versions of systemd and util-linux packages do you have? Could you attach the whole fstab?

Comment 2 patrick korsnick 2012-04-02 19:40:49 UTC

util-linux-2.21.1-1.fc17.x86_64
systemd-44-4.fc17.x86_64
systemd-sysv-44-4.fc17.x86_64

Comment 3 patrick korsnick 2012-04-02 19:55:52 UTC

Rebooting with setup in Comment 2 machine booted successfully. Must have gotten fixed sometime after the Alpha was released, because it was broken then. Closing bug as fixed.
