how to unmount disk after guix system init error?

[znavko]

Hello! I am trying to install Guix on other notebook. when I've parted it with fdisk using such partitions:
/dev/sdb1 50Gb Linux filesystem
/dev/sdb2 9Gb Linux swap

then `guix system init /mnt/etc/config.scm /mnt` gave the error:
Embedding is not possible. Grub can only be installed in this setup by using blocklists. However blocklists are UnreLIABLE and their use is discouraged.
guix system: error: failed to install bootloader

And this makes me sense need to do another partitioning like this:
/dev/sdb1 150Mb BIOS Boot
/dev/sdb2 50Gb Linux filesystem
/dev/sdb3 9Gb Linux swap

I cannot do this. I fullfilled this but making filesystem on /dev/sdb2 gives the error, that device is mounted.
As I understand this is because of my run 'herd start cow-store /mnt' and also run `guix system init .... /mnt`
I've stopped herd service. But do not know what to do else. So I can only reboot and start again.

Please is there another way to solve?

You're throwing away 149 MiB ;-)

Make this 1 MiB (at most), and give the rest to one of your other 
partitions instead.

Kind regards,

No, AFAIU there is no way other than restart the machine

I'm almost sure there's an already opened bug for this but I cannot find
it now :-S

HTH! Gio'
