Description of problem:
  Command `grub2-mkconfig -o /boot/grub2/grub.cfg` failed with message "/etc/tuned/bootcmdline: line 27: $'\n': command not found"

Version-Release number of selected component (if applicable):
  tuned-2.5.1-4.el7_2.6.noarch

How reproducible:
  always

Steps to Reproduce:
1. Have machine with at least 8 cpu
2. Do these steps:
   # mkdir /etc/tuned/custom
   # echo "[bootloader]
   cmdline=isolcpus=\${f:cpulist_invert:1-3,6}" > /etc/tuned/custom/tuned.conf
   # tuned-adm profile custom
   # grub2-mkconfig -o /boot/grub2/grub.cfg
  
Actual results:
   # grub2-mkconfig -o /boot/grub2/grub.cfg
   Generating grub configuration file ...
   /etc/tuned/bootcmdline: line 27: $'\n': command not found
   # echo $?

Expected results:
   End without error

   Failed test case:
   /CoreOS/tuned/Sanity/built-in-support-for-unit-conversion

Comment 3 Jaroslav Škarvada 2017-04-01 12:42:40 UTC
I cannot reproduce, machine with 12 cores, the grub2-mkconfig didn't fail, resulting cores:
$ grep TUNED_BOOT_CMDLINE /etc/tuned/bootcmdline 
TUNED_BOOT_CMDLINE="isolcpus=0,4,5,7,8,9,10,11"

It seems good, tested with both:
tuned-2.7.1-3.el7
and the latest tuned git head (v2.7.1-112-gdf9aa2f).

Could you provide content of the /etc/tuned/bootcmdline?
