On a router (busybox) I'm limited to shebang. On devices like these relaying on squashfs and flash storage it's common practice to mount --bind files from USB/CIFS/JFFS onto a file provided by the squashfs (and expanded in RAM).
e.g.
mount --bind /mnt/sda1/dnsmasq.conf /etc/dnsmasq.conf
I'm trying to automate some login in a script of mine but I can't find a way to display precisely what file was mounted --bind where?
the output of the mount command is incomplete in regard as it doesn't provide the full path of the source:
/dev/sda1 on /etc/sda1/dnsmasq.conf type fuseblk (rw,nodev,noatime,user_id=0,group_id=0,allow_other,blksize=1024)
As you can see the first column doesn't provide the full path of the source. df doesn't help either as the source is always /dev/sda1. So in a nutshell my question summarizes like this:
How do I go verifying what source file is "mount --bind" to what destination file?
Thanks!
