+## Chroot
+
+Because internal 8 GB storage is too small to install packages, I am using external USB3 SSD drive where I add Chroot of newest Debian Sid RISC-V.
+
+https://wiki.debian.org/chroot
+
+Remount with exec and dev so I can install Chroot. As root:
+```
+apt -y install debootstrap
+
+mkdir -p /media/sipeed/L500GB/debian
+
+mount -i -o remount,exec,dev /media/sipeed/L500GB
+
+debootstrap --no-check-gpg sid /media/sipeed/L500GB/debian http://ftp.ports.debian.org/debian-ports/
+```
