Once upon a time, Valeri Galtsev galtsev@kicp.uchicago.edu said:
All true, except for: to actually write stuff permanently to hard drive (that is modify whatever the content of hard drive is) the system needs to access /dev/sda1 (I call from now /dev/sda1 device which "/" filesystem lives on), and once /dev/sda1 is deleted there will be no further hard drive write operations.
Incorrect. Once the filesystem is mounted, the kernel access doesn't go through the filesystem /dev node, similar to how once rm is running, it doesn't need the /lib64/libc.so.6 node.
