I just went into
/etc/fstab (Linux) and changed my line for
/tmp (on which a specific
ext4 partition was previously mounted) to
tmpfs. This was clearly a bit silly, but I wasn't thinking. Anyway, I rebooted, and everything is working and all, but I'm confused about the following.
mount I see this:
/dev/sda8 on /tmp type tmpfs
Does this mean that
/dev/sda8 is mounted as
tmpfs? If there were any files in
/tmp, I can't access them any more, but I can create files in there. When I reboot, mounting as
ext4 I can see that there were in fact files on the partition (that weren't visible when
tmpfs was mounted).
Is the device file meaningless in this context?
