I want to create an overlay of the root directory and chroot into it to sandbox things like from source installs or runs, as well as other purposes.
I use the command..
mount -t overlay overlay -o lowerdir="/",upperdir="adirectory",workdir="anotherdirectory" chrootdir
What I get is an empty /home /dev /boot directory.
To me this seems the first purpose someone would use this feature for. The very first.
It seems it also warning against the next thing I would try that I do seem to remember is in fact a problem, where I’d simply create a different overlay for /home /dev etc., and bind mount it into the mergepoint. Which I am pretty sure failed.
Anyone else had any luck with this ?
Mounted directories inside lowerdirs not available in merged directory of overlayfs.
