Ubuntu / dropbox

 If you get the warning

Unable to monitor filesystem
Please run "echo 100000 | sudo tee /proc/sys/fs/inotify/max_user_watches" and restart Dropbox to correct the problem.

here's one way to increase the default value of /proc/sys/fs/inotify/max_user_watches at startup, so one doesn't have to do it manually at every boot.

As root (or with sudo), create a file

/etc/sysctl.d/30-inotify.conf

with the contents

fs.inotify.max_user_watches=100001

Reboot, or run "sudo service procps start".


That's it!
