Environmental Info:
K3s Version:
v1.31.2+k3s1

Node(s) CPU architecture, OS, and Version:
Any. Not relevant.

Cluster Configuration:
Various configurations. Not relevant.

Describe the bug:
The generated k3s-killall.sh and k3s-uninstall.sh scripts replace the current process with the same but running with sudo. This does not preserve the environment, i.e. a custom data directory using K3S_DATA_DIR is ignored.

Steps To Reproduce:

• Open a shell as non-root user
• Export environment variable K3S_DATA_DIR=$HOME/mydata
• Create a cluster in the same shell
• Run k3s-uninstall.sh in the same shell

Expected behavior:
Uninstallation should work properly. $K3S_DATA_DIR should be cleaned.

Actual behavior:
Instead of $K3S_DATA_DIR, /var/lib/rancher/k3s is used. $K3S_DATA_DIR is not cleaned. K3s is not properly uninstalled. This can be seen in the logs.
