Troubles formatting usb-flash under GuixSD, cause it cannot find mkfs.vfat.

I've installed dosfstools but util-linux installation shows some another stuff.

# guix package -i dosfstools
The following package will be upgraded:
 dosfstools 4.1 → 4.1 /gnu/store/4im5hyda53qjnkc869m0fxdi7dm5f0lg-dosfstools-4.1

nothing to be done

# guix package -i util-linux
The following package will be upgraded:
 util-linux 2.32 → 2.32 /gnu/store/fbaawq3xvpqpnj4rdhbiq8kmkmf6biqv-util-linux-2.32

# mkfs -t vfat /dev/sdb1
mkfs: failed to execute mkfs.vfat: No such file or directory

Sorry? Why all another filesystems present but vfat does not?

mkdosfs does not work too:

mkdosfs -F 32 -I /dev/sdb1
bash: mkdosfs: command not found

How to format to Fat 32 under GuixSD? I want just to burn flash with linux-iso.
