These are the instructions that I followed: https://willhaley.com/blog/custom-debia ... vironment/
I added several packages such as xorg, dbus, conkeror... to make it usable.
This works well, for the most part. It automatically logs 'user' into a windowlab session, and my email is setup and ready to go without intervention. Boot is faster than I've ever seen.
I post as I would like to know what these settings in /etc/fstab do:
Entire fstab file:
Code: Select all
# UNCONFIGURED FSTAB FOR BASE SYSTEM
overlay / overlay rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0
Apparently the overlay is 'rw,' but it does not hold the information. So 'rw' means that / can be read and written within the overlay? Also, will the space on the usb eventually be filled up by these settings? If so, I will be looking for a way (perhaps by mounting a certain way) to stop the filling up of data.
Thanks. And if anybody is curious about any information regarding the setup, feel free to ask!
