pam_systemd_home — Automatically mount home directories managed by
login, and unmount them on logout
pam_systemd_home ensures that home directories managed by systemd-homed.service(8) are automatically activated (mounted) on user login, and are deactivated (unmounted) when the last session of the user ends.
The following options are understood:
Takes a boolean argument. If true, the home directory of the user will be suspended automatically during system suspend; if false it will remain active. Automatic suspending of the home directory improves security substantially as secret key material is automatically removed from memory before the system is put to sleep and must be re-acquired (through user re-authentication) when coming back from suspend. It is recommended to set this parameter for all PAM applications that have support for automatically re-authenticating via PAM on system resume. If multiple sessions of the same user are open in parallel the user's home directory will be left unsuspended on system suspend as long as at least one of the sessions does not set this parameter. Defaults to off.
Takes an optional boolean argument. If yes or without the argument, the module will log debugging information as it operates.
The module provides all four management operations:
The following environment variables are initialized by the module and available to the processes of the user's session:
