I needed to specify a custom path for Roon’s database (in this instance a dedicated mSata SSD).
To specify a custom location edit the install script, search for
ROON_DATAROOT=/var/roon in the install script and replace
Note, there are two occurrences of ROON_DATAROOT=/var/roon in the script.
Obviously make sure the custompath is mounted via fstab during boot. When done, run the install script per Roon’s knowledgebase.
