The root filesystem(shortly RFS) is the filesystem that is contained on the same partition on which the root directory is located, and it is the filesystem on which all the other filesystems are mounted (i.e., logically attached to the system) as the system is booted up. The root filesystem should generally be small since it contains very critical files and a small, infrequently modified filesystem has a better chance of not getting corrupted.
e-con Systems™ has developed an image with tiny RFS containing the busybox commands and system startup scripts. The RFS arrives at a size of 9 MB!
e-con Systems™ has also developed an X11 image with tiny RFS. Refer Boot eSOMiMX6 with a Tiny RFS with X article to build a console image with minimal RFS of size 172 MB.
This article guides you to build a console image for eSOMiMX6 with a small root file system.
The root file systems contain the following necessary packages.
-
base-files
-
base-passwd
-
busybox
-
sysvinit
-
initscripts
These are very basic packages needed to work with eSOMiMX6. This image is not necessarily the smallest image that can be created, as many size reductions can be made with kernel changes, etc. When first starting a project, this is the fastest complete build, and it is also a good place to start to create a custom image.
Please visit our developer website to get step by step instructions to build the minimal console image for our eSOMiMX6 board.
