Do nothing about the folder, it is part of the system.
It is not 'virtual' it is very real.
But it only occupies some directory nodes in the system vfs, the contents are 'bind' mounts (typical contents of any chroot).
It has been there since early in the 5.x series of firmware.
It has nothing (at this time) to do with our jail break procedure.
It might make a jail break more difficult someday in the future, if Lab126 ever completes implementing whatever their plans are for it.
(It is currently a no-op.)
And since we have adopted the policy of: "No more public lessons given to Lab126", we don't discuss what/how it might be used to our disadvantage.
(or why it is not working as intended since it was introduced)
