what is /dev/loop0 for?
I am using Ubuntu. Today when I try to install a new package, Ubuntu notify me that I am running out of disk space.
I therefore did a df -h to take a look at the disk usage. What I notice is that it's the /dev/loop0 device getting full.
My question is, does /dev/loop0 work like the C:/ drive in windows. In other words, am I using space in /dev/loop0 when I install a package? I thought I am always using space in /dev/sdax, am I wrong about that?
