I want to mount several root folders on my 2GB SD card so that when the cord connecting my Mint hard drive falls loose, I won't have to reboot the system.
I have already mounted
/bin on the card. I know I can't really mount
/etc on the card because of the bootloading process, and I know that
/dev are temporary/fake directories.
What more folders (other than
/usr) can I mount on my SD card so that I don't have to reboot if the USB port lets the hard drive cord fall out?
