"No space left on device" but I have plenty of space left on device

I was getting this weird error: ``` [nix-shell:~/nixpkgs]$ nixglhost ipython Traceback (most recent call last): File "/nix/store/46qxb828xwxn8rgrhq7crdmanwf59fjk-nix-gl-host-0.1/bin/nixglhost", line 681, in <module> ret = main(args) File "/nix/store/46qxb828xwxn8rgrhq7crdmanwf59fjk-nix-gl-host-0.1/bin/nixglhost", line 629, in main new_env = nvidia_main(cache_dir, host_dsos_paths, args.print_ld_library_path) File "/nix/store/46qxb828xwxn8rgrhq7crdmanwf59fjk-nix-gl-host-0.1/bin/nixglhost", line 564, in nvidia_main cache_paths.append(cache_library_path(p, tmp_cache_dir, cache_dir)) File "/nix/store/46qxb828xwxn8rgrhq7crdmanwf59fjk-nix-gl-host-0.1/bin/nixglhost", line 449, in cache_library_path copy_and_patch_libs(dsos=dsos, dest_dir=d, rpath=rpath_lib_dir) File "/nix/store/46qxb828xwxn8rgrhq7crdmanwf59fjk-nix-gl-host-0.1/bin/nixglhost", line 331, in copy_and_patch_libs shutil.copyfile(dso.fullpath, newpath) File "/nix/store/zdba9frlxj2ba8ca095win3nphsiiqhb-python3-3.10.8/lib/python3.10/shutil.py", line 267, in copyfile _fastcopy_sendfile(fsrc, fdst) File "/nix/store/zdba9frlxj2ba8ca095win3nphsiiqhb-python3-3.10.8/lib/python3.10/shutil.py", line 156, in _fastcopy_sendfile raise err from None File "/nix/store/zdba9frlxj2ba8ca095win3nphsiiqhb-python3-3.10.8/lib/python3.10/shutil.py", line 142, in _fastcopy_sendfile sent = os.sendfile(outfd, infd, offset, blocksize) OSError: [Errno 28] No space left on device: '/usr/lib/x86_64-linux-gnu/libnvidia-eglcore.so.545.23.08' -> '/run/user/1000/tmpzgwq37ed/nix-gl-host/3076b0246cb1468199a8444860ebaebe5ec5081f85098057a9f4d5b40c3de738/lib/libnvidia-eglcore.so.545.23.08' [nix-shell:~/nixpkgs]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/root 31G 25G 6.8G 79% / devtmpfs 7.7G 0 7.7G 0% /dev tmpfs 7.7G 0 7.7G 0% /dev/shm tmpfs 3.1G 924K 3.1G 1% /run tmpfs 5.0M 0 5.0M 0% /run/lock /dev/loop0 25M 25M 0 100% /snap/amazon-ssm-agent/7628 /dev/loop1 56M 56M 0 100% /snap/core18/2812 /dev/loop2 64M 64M 0 100% /snap/core20/2105 /dev/loop3 87M 87M 0 100% /snap/lxd/26881 /dev/loop4 87M 87M 0 100% /snap/lxd/26975 /dev/loop5 41M 41M 0 100% /snap/snapd/20671 /dev/nvme0n1p15 105M 6.1M 99M 6% /boot/efi tmpfs 1.6G 20K 1.6G 1% /run/user/1000 ``` Oddly, it seems to have gone away now, despite not having changed my configuration. Not sure what might be going on, or how to reproduce consistently, but hoping that creating this issue will help to spur discussion.
