I have mounted a directory with the following command
sudo unionfs -o cow,max_files=32768 -o allow_other,use_ino,suid,dev,nonempty stuff-linux64=RW stuff
How do I change stuff-linux64 from RW to RO and add another directory (stuff-update64) on top?
The end result should look like I'd executed:
sudo unionfs -o cow,max_files=32768 -o allow_other,use_ino,suid,dev,nonempty stuff-update64=RW:stuff-linux64=RO stuff
after unmounting stuff.
For that matter, how do I unmount a filesystem that I mounted with unionfs?
