Regression: bcvk fails systemd-boot installation: Cannot allocate memory

[travier]

Using latest bcvk built from git here and downloaded with ORAS (https://github.com/bootc-dev/bcvk/blob/main/docs/src/installation.md#development-binaries), the following commands fails:

./bcvk libvirt run --name bootc-test --detach --firmware=uefi-secure --secure-boot-keys=$PWD/secureboot/keys --label=bootc.test=1 --filesystem=btrfs --composefs-backend --bootloader=systemd localhost/uki

With:

...
Bootloader: systemd
Installing bootloader via systemd-boot
Running in a chroot, enabling --graceful.

    args: [

        "/tmp/.tmpulGeO5",
    ],

}

With bcvk 0.10.0 from Fedora and the same container image and same command, it goes pass that step. I have not bissected the issue yet.
