Description Tereza Cerna 2017-05-24 11:59:25 UTC

Description of problem:
=======================
There is parser with no limits for variable initrd_remove_dir. By description, it should check something like 'True', 'true' and '1' and then remove specified directory. However it removes directory for all values of this variable. I tried 'True', 'true', '1', 'False', 'false', '0', '/root/image' or 'blabla' and it removes this directory for all these values.


Version-Release number of selected component:
=============================================
tuned-2.8.0-2.el7.noarch


How reproducible:
=================
Always


Steps to Reproduce:
===================
# cat /usr/lib/tuned/test-profile/tuned.conf 
[bootloader]
initrd_add_dir=/root/image
initrd_dst_img=/boot/test-tuned-2.img
initrd_remove_dir=blabla

# find /root/image
/root/image
/root/image/etc
/root/image/etc/aaa

# tuned-adm profile test-profile

# cat /var/log/tuned/tuned.log 
2017-05-24 07:04:25,872 INFO     tuned.daemon.daemon: stopping tunning
2017-05-24 07:04:26,072 INFO     tuned.profiles.loader: loading profile: test-profile
2017-05-24 07:04:26,073 INFO     tuned.daemon.daemon: starting tuning
2017-05-24 07:04:26,076 INFO     tuned.plugins.plugin_bootloader: generating initrd image from directory '/root/image'
2017-05-24 07:04:26,080 INFO     tuned.plugins.plugin_bootloader: installing initrd image as '/boot/test-tuned-2.img'
2017-05-24 07:04:26,081 INFO     tuned.plugins.plugin_bootloader: removing directory '/root/image'
2017-05-24 07:04:26,082 INFO     tuned.daemon.daemon: static tuning from profile 'test-profile' applied

# ls /root | grep image


Actual results:
===============
# cat /var/log/tuned/tuned.log 
...
2017-05-24 07:04:26,081 INFO     tuned.plugins.plugin_bootloader: removing directory '/root/image'
...


Expected results:
=================
It can't remove anything. There is no valid value in variable initrd_remove_dir in profile configuration file. It should remove /root/image only if this variable is set to 'True', 'true' or '1'.


Additional info:
================
I tried these values of initrd_remove_dir:
  initrd_remove_dir=True
  initrd_remove_dir=true
  initrd_remove_dir=1
  initrd_remove_dir=/root/image
  initrd_remove_dir=False
  initrd_remove_dir=false
  initrd_remove_dir=0
  initrd_remove_dir=blabla

For all these options, directory /root/image was removed.
