Booting a Linux system off USB Pendrives is one of my favorite things.
On a laptop we have the following advantages,
- The Harddisk can be shutdown and that reduces power consumption (hdparm)
- The system heats lesser and the fans are triggered less frequently
- The system can take more shocks (a bumpy backseat taxi ride)
With old workstation hardware,
- Can be used for quick testing of the hardware platforms
- Linux (Ubuntu these days) works quite well with most hardware
- One Downside: Many old motherboard BIOS do not support a USB boot
I have preferred a USB "boot-stick" to a LiveCD in most cases.
- What other advantages and problems have you seen or anticipate with USB booted Linux?
- What is your choice of Linux for this purpose?
- Would you suggest
ext4or something more proven/stable for a linux usb-boot?
- Do you often find USB drives getting corrupted?
- Do you partition your USB drives?
