Booting Debian from a RAM disk

This guide is adapted from http://reboot.pro/topic/14547-linux-load-your-root-partition-to-ram-and-boot-it/

What you need:

• lots of RAM
• Debian based distribution or any that supports booting from initramfs
• mkinitramfs or a tool to build a new initramfs
• some linux knowledge
• no need to create an image
• no need for Grub4Dos

Below is my understanding of affine types and how they help us in Rust (unsure if I got this right - please correct if I am talking nonsense).

The issue is... How can we use the power of a type system so a compiler will block us from doing this wrong sequence of calls?

FILE *fp = NULL;
fclose(fp);
fp = fopen("...");

An idea is to "mirror" the states that the file variable goes through (unused/closed, opened) in the type system:

            OleDbCommand cmd = new OleDbCommand("select * from [Sheet1$]", conn);
            conn.Open();
            OleDbDataReader dr = cmd.ExecuteReader();

scp -C production:~/database.sql.gz
dropdb database && createdb database
