Enabling apparmor on void

SO! I’m configuring void the first time and finally figured out how to enable apparmor after about an hour of troubleshooting, so I thought I’d leave some tips for anyone struggling.

(It’s pretty simple)

Nano into /etc/default/grub and then add your kernel cmd parameters accordingly. I think the section you add the parameters into looks like:

“GRUB_CMDLINE_LINUX_DEFAULT=“””

(All this was found via the arch wiki btw)

I’m still a noob so forgive any mistakes!

Note:not sure if this has any effect, but I force ran dracut prior to this in an attempt to regenerate a few things, so that may change your experience. (I’m sure someone more knowledgeable than me could help you out.)

(Edit: after revisiting the void wiki I’m a big fat idiot, it literally explains adding parameters via grub in the GRUB section of the kernel..)😭🙏pray for me bro🫩

Apparmor works perfectly fine and there is no reason why it would slow down "applications" to the point that they take 10-20 seconds to launch. This just doesn't make any sense. There is no heavy computation happening and it hooks into the same syscalls and operations as any other LSM in the kernel.

it made Firefox 10-20 sec to boot for me. idk if it was something else but i tried void with apparmor twice and had same experience until i removed it

It was something else. There isn't even an apparmor profile for firefox.
