I want to understand how can I figure out the actual source of a mount from /proc/self/mountinfo file?
Here is an example of a mountinfo file:
19 60 0:5 / /dev rw,nosuid shared:2 - devtmpfs devtmpfs rw,seclabel,size=1930460k,nr_inodes=482615,mode=755
119 74 0:5 /sda1 /home/abc/def rw,nosuid shared:2 - devtmpfs devtmpfs rw,seclabel,size=1930460k,nr_inodes=482615,mode=755
Here from the first entry we can see that devtmpfs is mounted to /dev.
In the next line we can that devtmpfs is mentioned as the source. But we already know that it is mounted on /dev. So what should be the real mount source for /home/abc/def?
Should it be /dev?
