remove superfluous space from test line 315

RedHat uses a different configuration name 2018-01-08 12:59:12 +01:00
Vincent Brillault
66f7708095
Refactor RedHat support: 
- Isolate file check to different elif (allowing to add more)
- Do the PTI debugfs check first (faster and supposed to be dynamic)
- If pti_enable is 0, don't trust dmesg (supposed to be dynamic)

1aaca63dcf Improve "running as root" check 
Small issue with the USER environment variable:

  $ echo $USER
  thib
  $ sudo sh -c 'echo $USER'
  thib
  $ sudo -i sh -c 'echo $USER'
  root

Rather than recommending users to use sudo --login / -i, use the (very
widespread/portable) id program to retrieve the effective user ID
instead and don't change the recommendation.

  $ id -u
  1000
  $ sudo id -u
  0
  $ sudo -i id -u
  0
