bug#68561: Guix wrongfully claims there is no space left

[Lars Rustand]

Guix is claiming that there is no space left on the device when none of
my devices are in fact full. As you can see from the output of df -h
there is more than enough space on all filesystems:


Filesystem      Size  Used Avail Use% Mounted on
none            7.8G     0  7.8G   0% /dev
/dev/nvme0n1p7  250G  159G   79G  67% /
/dev/nvme0n1p1  2.0G  428K  2.0G   1% /boot/efi
tmpfs           7.8G  281M  7.5G   4% /dev/shm
efivarfs        184K  137K   43K  77% /sys/firmware/efi/efivars
none            7.8G   24K  7.8G   1% /run/systemd
none            7.8G     0  7.8G   0% /run/user
tmpfs           1.6G  8.0K  1.6G   1% /run/user/1000


This is the build output from Guix when trying to reconfigure my home:
