Can overlayfs follow mounts in lowerdir?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I'm trying to use overlay to create temporary virtual root filesystem.
I need a copy of / with custom files on top of it.

To achieve that I used a simple mount like this:
mount -t overlay overlay -o lowerdir=/,upperdir=/tmp/ov/upper,workdir=/tmp/ov/work /tmp/ov/virtual

In /tmp/ov/virtual/ I can see my main filesystem and I can make temporary
changes to it. Almost perfect!

The problem are mounts. I have some standard ones:
proc on /proc type proc (rw,nosuid,nodev,noexec,noatime)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,noatime)
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noatime)

They are not visible in my virtual root:
# ls -l /tmp/ov/proc/
# ls -l /tmp/ov/sys/
# ls -l /tmp/ov/tmp/
(all empty)

Would that be possible to make overlayfs follow such mounts in lowerdir?
