[FEAT] setup $PATH for root user

[fkjaekel]

Using the role with the default variable values, ansible playbook running with become=true

$ gu install native-image
Error: Insufficient privileges for administration of the GraalVM installation. You need to become "root" user to perform administrative tasks on GraalVM. 
NOTE: depending on your operating system, you may need to use OS tools to install or uninstall GraalVM components.

Trying to run as root:

$ sudo gu install native-image
sudo: gu: command not found

Hello @fkjaekel ,

I understand your problem. I run always into the same problem and fix it manually.

I think the Java 21 feature is more important for you. So I will work on this one first
And then go on with this one

Hi @fkjaekel ,
just for your information: With version 21 the gu tool is removed
oracle/graal#6855

Hello @fkjaekel ,
please give me a hint how to solve your problem?

what can I do:
add symlinks to /root/.local/bin for all files in /opt/graalvm/jdk-XX.Y.Z/bin/*
-> my prefered solution because this should work over all distros and not only when using bash

or add the GRAALVM_HOME variable to the .bashrc of root and then add it to the path like this:

export GRAALVM_HOME='/opt/graalvm/jdk-XX.Y.Z'
export PATH=${GRAALVM_HOME}/bin:${PATH}

Both solution would not help in your case. and only when you switch to root completly.

let me demonstrate this for

# switch to root user explicitly
arl@fedora ~ $ sudo su -
[root@fedora ~]# java --version
openjdk 21 2023-09-19
OpenJDK Runtime Environment GraalVM CE 21+35.1 (build 21+35-jvmci-23.1-b15)
OpenJDK 64-Bit Server VM GraalVM CE 21+35.1 (build 21+35-jvmci-23.1-b15, mixed mode, sharing)
[root@fedora ~]# which java
/root/.local/bin/java
[root@fedora ~]# exit
logout
arl@fedora ~ $ sudo java --version
openjdk 17.0.8 2023-07-18
OpenJDK Runtime Environment (Red_Hat-17.0.8.0.7-1.fc37) (build 17.0.8+7)
OpenJDK 64-Bit Server VM (Red_Hat-17.0.8.0.7-1.fc37) (build 17.0.8+7, mixed mode, sharing)
arl@fedora ~ $ sudo which java
/usr/bin/java
arl@fedora ~ $ sudo ls -la  /usr/bin/java
lrwxrwxrwx. 1 root root 22 Sep  4 07:45 /usr/bin/java -> /etc/alternatives/java

What I don't want to interfere with the java alternatives

A simple workaround for you could be

# here I switched my graalvm to 17.0.8
# the GRAALVM_HOME Variable is set in normal circumstances
arl@fedora ~ $ sudo $GRAALVM_HOME/bin/gu --version
GraalVM Updater 23.0.1

I'm waiting for your feedback

Hi,

Option 1 sounds fine. Since native-image is now included, I currently don't have other components to install after the GraalVM setup.

Thanks
