Guix,

This is weird.  On berlin:

--8<---------------cut here---------------start------------->8---
$ guix build 
/gnu/store/91wjmydy556ibl38xydpb8yisp3gvx8w-partition.img.drv
[…]
Creating filesystem with 351 1k blocks and 40 inodes
[…]
/gnu/store/q18ca3ilma0h5hpn4s39xhzn0kc7jm5x-partition.img
--8<---------------cut here---------------end--------------->8---

On my laptop:

--8<---------------cut here---------------start------------->8---
$ guix build 
/gnu/store/91wjmydy556ibl38xydpb8yisp3gvx8w-partition.img.drv
[…]
Creating filesystem with 242 1k blocks and 32 inodes
[…]
Copying files into the device: ext2fs_symlink: Could not allocate 
inode in ext2 filesystem while creating symlink "system"
__populate_fs: Could not allocate inode in ext2 filesystem while 
writing symlink"system"
mke2fs: Could not allocate inode in ext2 filesystem while 
populating file system
--8<---------------cut here---------------end--------------->8---

This happens with both a tmpfs and a bcachefs /tmp.

The same make check-system TESTS="openvswitch" fails for Marius as 
well, although I don't know the exact output.  They tested btrfs 
and tmpfs, and suggested a kernel regression.

I don't understand how that would cause this, but I'm forced to 
agree: something spooky is going on in the chroot and the kernel 
is a big variable.

The attached patch was written before I was aware of above 
weirdness and only works around the issue.

Kind regards,

T G-R
