On Guix =E2=80=94sorry for the shameless publicity for Guix!=E2=80=94, we h=
ave a way to
offload package builds from a host to a ChildHurd [1]. Basically,
it=E2=80=99s a Hurd VM.

[1]: https://guix.gnu.org/en/blog/2020/childhurds-and-substitutes/

It was working fine until I ran short of disk space and increased it to
20Gb. Now, it randomly crashes with error messages like:

```
ext2fs: BUG: unexpected fault on disk image (10, 0x8ffc000) in
[0xB8222000,0x18222000) eip 0x8052224 err 0xa
```

or:

```
ext2fs: disk-pager.c:109: fault_handler: Assertion =E2=80=99err=E2=80=99 fa=
iled.
```

Now that I know I=E2=80=99m not hitting the disk size limit =E2=80=94thanks=
 for
pointing to the FAQ!=E2=80=94, I=E2=80=99m wondering what the problem might=
 be?
Any idea?!
