error: rmdir: Device or resource busy

Hello,

tried installing GuixSD 0.16. But hitting a cryptic error.

guix system init /mnt/etc/config.scm /mnt
--substitute-urls="http://berlin.guixsd.org http://mirror.hydra.gnu.org"
...
/gnu/store/sh9x3mhl5q60yxhl861kpk6vm70l3w81-bootloader-installer

initializing operating system under '/mnt'...
guix system: error: rmdir: Device or resource busy

This was working fine with 0.15.

Is there a way to get a better backtrace from system init? Or does anyone
know what the error might be?

Thanks

Yes!

From the manual: 
'--on-error=STRATEGY'
     Apply STRATEGY when an error occurs when reading FILE.  STRATEGY
     may be one of the following:

     'nothing-special'
          Report the error concisely and exit.  This is the default
          strategy.

     'backtrace'
          Likewise, but also display a backtrace.

     'debug'
          Report the error and enter Guile's debugger.  From there, you
          can run commands such as ',bt' to get a backtrace, ',locals'
          to display local variable values, and more generally inspect
          the state of the program.  *Note (guile)Debug Commands::, for
          a list of available debugging commands.

Actually the --help to "guix system" hints about this but it is not
telling how to use it, which is a bug I think. (i'm going to report it
and send a patch)

I never saw it before.

Tackar! Completely missed that option when I checked --help. But it
looks like that option doesn't do anything for me. Still got the same
error message.

Me neither. I ended up just installing guix-0.15 instead.  Did a guix
pull to --branch=version-0.16.0 (I hope that is equivalent). And
currently waiting for it to finish reconfigure.

Got carried away with just playing around with the system, after I
installed 0.15. Really nice system I must say. Only crucial package I'm
missing is polybar. At the moment, having a hard time keeping track of my
windows in i3 :). But I figured that will be a good introduction in packaging
stuff for guix.

Anyway, thanks for the help again!
