I wanted to remove a symlink from /sbin/ directory. The link is swapon which is linked to busybox binary on the same directory.
While trying to remove first-time, it said "Read only filesystem". So, I remounted / with read-write using this command
mount -o remount,rw /
Then I was able to remove it. I checked with which swapon as well as using ls. All fine. Now, when I rebooted the phone, the link appeared in the same location magically!
Am I missing something? What's happening here? How do I remove this link?
Here is the output of mount in case it is required
