I read the part "Use A Scratch Disk For Faster Builds" at Tips For Faster Rust Compile Times | corrode Rust Consulting but I cannot understand how to mount that volume in a fresh linux setup.
Can you please help me understand how to do that exactly?
Did you try this?
I added this in my /etc/fstab:
tmpfs /home/blonk/tmp tmpfs nodev,nodiratime,size=16384M 0 0
(And then set target-dir in cargo's config to /home/blonk/tmp/bld/cargo)
Thanks, but I think he suggests to avoid tmpfs, right?
Sorry I'm not a Linux expert.
They suggest using a dedicated disk due to large artifacts and the like. If your RAM isn't enough and/or you just want to follow that suggestion, the first step would be obtaining a dedicated disk.
Right, sorry -- I just read "faster rust compile times" and "mount" and assumed the suggestion was to use tmpfs.
But the principle is basically the same -- you stick the mount in /etc/fstab. The thing he posted is the options field. You should create a ext4 partition for the scratch data, then add an ext4 entry to /etc/fstab for that partition, but with the added mount options they suggested.
(Note: There may be other ways to add mounts to Linux systems, but I assume you're using a mainstream distro).
With all that said, I strongly disagree with the tip not to use a tmpfs. The only time it has caused me problems is when I build many large crates without a cargo clean between builds. But if you're looking to have faster builds and avoid wear and tear on your persistent storage, then use a tmpfs.
