http://linuxexchange.org/questions/2861/how-do-i-force-upperdir-overlayfs-to-rereadreload-lowerdir<p>i am having the following problem with an overlayfs: I can mount an overlayfs fine using the following line in my etc/fstab</p> <pre><code>none /home/student overlayfs lowerdir=/home/student,upperdir=/home/.student_rw 0 0 </code></pre> <p>this works great and the mount command displays the overlayfs corretly:</p> <pre><code> pc:~$ mount -l -t overlayfs none on /home/student type overlayfs (rw,lowerdir=/home/student,upperdir=/home/.student_rw) </code></pre> <p>so now when a student logs out of the machine i delete the contents of /home/.student_rw using a script - which also works fine.</p> <p>the problem is that the student logging in, should find a clean home directory with the settings preconfigured in (/home/student) as the overlayfs does not touch the lowerdir folder.</p> <p>the exact same approach worked very well for aufs, which are no longer supported in precise.</p> <p>interestingly, the overlayfs approach works fine as long as i reboot the machine. so how can i fix this problem? for me a possible solution seems to be to let the upperdir reread the lowerdir. how would i do that?</p> <p>thanks</p>enFri, 20 Jan 2017 14:58:29 -0000
