TARGET         SOURCE  FSTYPE  OPTIONS
/sys/fs/cgroup cgroup2 cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate,memory_recursiveprot

The issue is related to new cgroup v2. To resolve this, revert cgroup to v1:

sudo sed -i '/^GRUB_CMDLINE_LINUX/ s/"$/ systemd.unified_cgroup_hierarchy=0"/' /etc/default/grub

and reboot.

After this /sys/fs/cgroup/memory/memory.limit_in_bytes will be present.

upstream issue NixOS#333219 - ping @Nika03

the download url for install.sh seems to be stable for different users at cudominer.com

Hi, I just wanted to let you know that I'm only a user. I used this software on Windows but I haven't tried to use it on Linux since I use NixOS as my primary OS. CudoMiner was made primarily for Ubuntu as far as I'm aware. I haven't tried packaging software for Nix.

Here is a screenshot of the download page from CudoMiner for Ubuntu

Here is the line of bash as text:
sudo su -c "bash <(wget -qO- https://download.cudo.org/tenants/135790374f46b0107c516a5f5e13069b/5e5f800fdf87209fdf8f9b61441e53a1/linux/x64/stable/install.sh)" root

I don't think I can be of assistance. Sorry.

all good : )
i just wanted to share my progress
waiting for NixOS#333219 could take forever, because low priority

download page from CudoMiner

yepp, i have a user account at cudominer.com, and i get the same url for install.sh

a possible workaround for the cgroup2 error would be to downgrade to cgroup1
as described on stackoverflow
but i hope that cudominer will fix their code in the near future...
