VIM4 kernel bootargs user config
Introduction
This page mainly introduces how-to user can customize linux kernel bootargs under Ubuntu.
Add User Configuration
You can edit file /boot/uEnv.txt to add the user bootargs.
The default file contents are similar as below:
$ cat /boot/uEnv.txt
#############################DO NOT TOUCH THIS OPTION#############################
rootdev=root=UUID=a92f7f2f-0d4a-4607-a45a-4549cfe71036
partitiontype=partition_type=generic
#############################DO NOT TOUCH THIS OPTION#############################
## Add user args here, spilt with space.
## e.g. Add bootargs 'test1=111 test2=222'
## boot_user_args=test1=111 test2=222
boot_user_args=
You can append your bootargs to node boot_user_args=.
e.g. Add bootargs cgroup_enable=cpuset cgroup_memory=1 cgroup_enable=memory systemd.unified_cgroup_hierarchy=0, the node boot_user_args= should be as below:
boot_user_args=cgroup_enable=cpuset cgroup_memory=1 cgroup_enable=memory systemd.unified_cgroup_hierarchy=0
Please make sure the bootargs are spilt with space and don't add quotation marks.
Save the file and reboot to take effect.
Check User Configuration
After reboot and login the system, you can check whether the bootargs you added exist in the system node.
$ /proc/cmdline
