SparkOS - Minimal Linux Distribution
|
|
====================================
|
|
|
|
Available commands:
|
|
ls, cd, pwd - Navigate filesystem
|
|
cat, less - View files
|
|
mkdir, rm, cp - File operations
|
|
mount, umount - Mount filesystems
|
|
poweroff, reboot - System control
|
|
help - Show this help
|
|
|
|
This is a minimal system. To extend functionality:
|
|
1. Mount additional filesystems
|
|
2. Install packages (if package manager available)
|
|
3. Build from source
|
|
|

SparkOS Root Filesystem
|
|
=======================
|
|
|
|
This is the root filesystem for SparkOS, a minimal Linux distribution.
|
|
|
|
Directory Structure:
|
|
/bin, /sbin - Essential binaries
|
|
/etc - Configuration files
|
|
/proc, /sys, /dev - Kernel interfaces
|
|
/tmp - Temporary files
|
|
/usr - User programs
|
|
/var - Variable data
|
|
/root - Root home directory
|
|
/home - User home directories
|
|
|
|
Note: This is a minimal system. You'll need to populate /bin and /usr/bin
|
|
with actual binaries (busybox, etc.) from a proper Linux system
|
|
or by cross-compiling.
