It would be better if guix gc could run on a disk that was completely
full, as right now it cannot be used to free space on a full disk.

The daemon reserves a bit of extra space before starting operation (see
‘reserve-space?’ in (guix store)), which should be enough to gracefully
handle situations where builds are filling the disk.
However, there can also be non-Guix processes filling the disk, to the
point where it’s completely full, and at that point sqlite3 (which the
daemon uses) may be unable to operate.
I’m afraid there’s little we can do in this case.
Thoughts?

I didn't experience this. Guix pull filled the disk, which prevented
the gc from working. It's possible some other process was writing in
the background, but I had built an image which was almost completely
devoid of programs and services.

Copy the database into tmpfs temporarily?

Hello,
for the guix daemon sqlite problem, could we
preallocate some space in the database also ?
