To specify the following to Greyhole in greyhole.conf:
{{Text|Text=<pre>sticky_files <nowiki>=</nowiki> Music/
 sticky_files <nowiki>=</nowiki> Videos/Movies/
     stick_into <nowiki>=</nowiki> /mnt/hdd1/gh
     stick_into <nowiki>=</nowiki> /mnt/hdd5/gh
 sticky_files <nowiki>=</nowiki> Backups/CrashPlan/
     stick_into <nowiki>=</nowiki> /mnt/hdd0/gh}}</pre>
one should specify this in the greyhole.yml file, where '''precise indentation matters''':
{{Text|Text=<pre>sticky_files: 
 - - Music/
 - - Videos/Movies/
     - /mnt/hdd5/gh
 - - Backups/CrashPlan/
   - - /mnt/hdd0/gh}}</pre>
For your changes to be effective, you'll need to force Amahi to regenerate the greyhole.conf file. You can do so by editing a share, clicking it's path, and just clicking the Save button without actually changing the path.
