Wrong processing kernel options without assignment in 'cobbler edit profile ... --in-place' command

[Albert Syriy]

Editing a cobbler profile kernel options with the key --in-place for the kernel options without assignment (=value) follows to the adding assignment the '~' value.

For example:

Original kernel options (please put your attention to the 'toram' and 'debug' options):
-------------------------------------------------------------------------------
initrd=/images/ubuntu_bootstrap/initrd.img ksdevice=bootif console=ttyS0,9600 console=tty0 toram debug
-------------------------------------------------------------------------------

After executing the cobbler command
-------------------------------------------------------------------------------
cobbler profile edit --name ubuntu_bootstrap --kopts="console=tty0 console=ttyS0,115200 iommu=off" --in-place
-------------------------------------------------------------------------------

Will be mangled to (please put attention to the 'toram' and 'debug' options):
-------------------------------------------------------------------------------
initrd=/images/ubuntu_bootstrap/initrd.img ksdevice=bootif console=ttyS0,115200 console=tty0 iommu=off toram=~ debug=~
-------------------------------------------------------------------------------

Adding =~ to the toram changes the option from a flag downloading file system into the RAM to the name of the file-system file (with the name '~') and triggers kernel panic.

See the bug for the details

So kernel flags like debug, loglevel, toram and etc should not be mangled with the '=~' value.

Details about cobbler version:

# cobbler version
Cobbler 2.6.9
  source: ?, ?
  build time: Mon May 23 15:48:50 2016

IMHO the check of '~' in profile and removing (all '~') before saving new parameters should be add into the code lines:
