Hello,
I have a rather unusual query.
Consider that i have a readonly filesystem mounted at / and that the
/etc folder consists of some files. Is is possible to mount a ramfs
filesystem at /etc such that the existing files in the /etc partition
are still accessible and any new files written to
What you are looking for is sometimes called union file system. There
exist some variations of such file systems, unfortunately there is none
in the official kernel. It seems that Linus doesn't like the idea.
Of course this is not related to busybox.
You may want to look at the implementation
Thanks for the quick response. I will check out the links Bartos provided.
Certainly, my query is not related to busybox, but where else can i

Hi Eduardo !
Yes that's possible just bind mount a tmpfs dir. So create a tmpfs
somewhere eg. /tmpfs then mount -o bind /tmpfs /etc.
This is incorrect. If you mount a file system this way you replace the
original contents of the directory with contents of the new file system.
