Domtool has user-specified configuration files that determine how to set up a domain or subdomain. Each file contains all of the information needed to configure a single domain.
If you want Domtool to process these files automatically, then place them in the ~/.domtool directory. If you are just testing out a domain temporarily, the configuration files may be placed anywhere.
By default, this ~/.domtool directory is actually a symlink to the ~/.public/.domtool directory. This makes your configuration files readable by anyone, but writable only by you. If you want to make them private, then do the following.
rm ~/.domtool mkdir ~/.domtool fs setacl ~/.domtool domtool read # Do the following two commands if you have any files in ~/.public/.domtool mv ~/.public/.domtool/* ~/.domtool rmdir ~/.public/.domtool
