The user-db program

user-db compiles the source directories of the user configuration directory into the compiled format. This format can then be used by init and user-rc to set up and control a user supervision tree.

user-db is a wrapper around the more general compile-db making it target the user supervision tree.

Interface

     user-db

• user-db takes no arguments.
• It reads the USER environment variable, if it is empty it exits 100.
• It reads the USERTREE environment variable, if it is empty it exits 100.
• It reads the HOME environment variable, if it is empty it exits 100.
• It runs compile-db supplementing it the correct user configuration directory and user runtime directory.

Exit codes

• 100 if a critical environment variable is missing.
• Since user-db is a wrapper around compile-db, it behaves exactly like it.

Options

• There are no options to user-db.
