@Gekko0114 I'm trying to remove inti_* in the selinux crate. WDYT? If you agree with me, I'll continue going on this PR.

What do you mean by inti_* in the selinux crate ?
I couldn't find any functions or values with the prefix inti_.

Ops, like policy_root_init_done

I see. I am not familiar with Rust, therefore it is possible that there should be better implementation rather than using atomicBool.
Thanks, I will wait for your PR :)

I've pushed my changes. Overall, I have already finished it, but I still need to edit it to run it on VM.

@Gekko0114 I couldn't completely run main.rs on VM based on Vagrantfile, even if it's in the main branch. Did you pass it?

Hi @utam0k
I noticed this message now, so sorry for late reply. I will have a look.

Hi @utam0k

Though I am using libvirt instead of virtualbox because of my PC environment, I could run the code.

selinux is enabled
default enforce mode is: enforcing
current enforce mode is: enforcing
SELinux label of current process is: unconfined_u:unconfined_r:unconfined_t:s0-s0
file label is system_u:object_r:public_content_t:s0

Based on previous comments from YJDoc2, it appears this error is likely related to directory mounting within Vagrant, rather than an issue with the code itself. YJDoc2 found that copying the binary to /tmp resolved the issue, indicating that the problem arises from how Vagrant mounts directories.
#2900 (comment)

Hmm, the issue was that with the directory mounting. When I copied the binary into /tmp it worked correctly as expected and sets the label. This is probably issue with mounting dirs into vagrant, not not with our code, so can ignore. Going ahead and merging this PR. Thanks a lot!

Therefore, while the error is occurring, it seems to be an environmental issue rather than code issue.
What do you think?
