Description:
Hi I am trying to build a package in void linux chroot (because I don't use void as my main system but I need it to test packages) 

First I had problems with my kenel not supporting the for the ```unshare``` command
CONFIG_NAMESPACES
CONFIG_IPC_NS
CONFIG_UTS_NS
CONFIG_USER_NS

After fixing that, the error became something saying (permission denied)

Then I run these commands:

```
chown root:<xbuilder> $(which xbps-uchroot)
chmod 4750 $(which xbps-uchroot)
usermod -a -G <xbuilder> root
```

And now the error is 
ERROR: Failed to mount / private (Invalid argument)

Please help me, I don't care about user permissions I run everything as root. Permissions are bloat, that I don't care about. I just want to get stuff done and move on with my day. Please stop making this harder than it needs to be and make the root do everything I need, without all this user group bullshit. 

If you can't fix your xbps-src script, then just take a look at this issue here: I need someone to test this bug in the package
