Bug Description
Found an issue when we try to get correct console on bootstrap images with the below command in MOS 9.0
cobbler profile edit --name bootstrap --kopts=
It worked well in MOS 7.0 and MOS 8.0, but since in MOS 9.0 there is no profile with name bootstrap we replaced it with
cobbler profile edit --name ubuntu_bootstrap --kopts=
Then the following issue is observed and nodes were not discovered.
During boot from bootstrap image we get the kernel panic
After inspecting the init procedure we realized that initrd.img tries the following:
mount -t devtmpfs -o mode=0755 udev /dev
mount -n -o move /dev ${rootmnt}/dev
rm -rf /dev
ln -s ${rootmnt}/dev /dev
The rm command deletes both /dev and /root/dev directories and the ln creates a recursive symlink to itself.
Also strange that the downloaded fetch parameter is not used anywhere.

Hello, could you please provide output from:
cobbler profile report --name ubuntu_bootstrap |grep -i 'Kernel Options'
If it was default bootstrap, you should find option:
'panic': '60',
If you need to disable panic reboot- you should remove this option
@asiryi could you suggest something more ?
