For specific configuration requirements of the /dev/shm mount for your environment, modify /etc/fstab. Example: tmpfs /dev/shm tmpfs defaults,rw,nosuid,nodev,noexec,relatime,size=2G 0 0 Note: Using Btrfs subvolumes instead of traditional disk partitions changes how disk space is allocated and enforced, quotas may need to be configured to enforce storage limits and prevent resource exhaustion.
