This commit deprecates profile management from the activation script. The profile management is instead the responsibility of the driving software, for example, the `home-manager` tool in the case of standalone installs. The legacy behavior is still available for backwards compatibility but may be removed in the future. The new behavior resolves (or moves us closer to resolving) a number of long standing open issues: - `home-manager switch --rollback`, which performs a rollback to the previous Home Manager generation before activating. While it was previously possible to accomplish this by activating an old generation, it did always create a new profile generation. This option has been implemented as part of this commit. - `home-manager switch --test`, which activates the configuration but does not create a new profile generation. This option has _not_ been implemented here since it relies on the current configuration being activated on login, which we do not currently do. - When using the "Home Manager as a NixOS module" installation method we previously created an odd `home-manager` per-user "shadow profile" for the user. This is no longer necessary. This has been implemented as part of this commit. Fixes #3450

.Sh DESCRIPTION
|
|
.Pp
|
|
This command updates the user environment so that it corresponds to the configuration specified in
|
|
$XDG_CONFIG_HOME/home-manager/home.nix
|
|
or
|
|
$XDG_CONFIG_HOME/home-manager/flake.nix.
|
|
.Pp
|
|
All operations using this tool expects a sub-command that indicates the operation to perform. It must be one of
|
|
.Pp
|
|
.Bl -tag -width Ds
|
|
|
|
.It Cm build
|
|
.RS 4
|
|
Build configuration into a result directory.
|
|
.RE
|
|
|
|
.It Cm init Op Fl -switch Op Ar dir
|
|
.RS 14
|
|
Generates an initial home.nix file for the current user. If Nix flakes are
|
|
enabled, then this command also generates a flake.nix file.
|
|
.sp
|
|
If a path
|
|
.Ar dir
|
|
is given then the configuration will be generated in that directory. Otherwise, the configuration will be generated in
|
|
~/.config/home-manager. The output directory will be created if it does not exist.
|
|
.sp
|
|
If the
|
|
.Fl -switch
|
|
option is given, then the generated configuration is activated.
|
|
.sp
|
|
Note, this command will not overwrite any existing files. It is therefore safe to initialize a configuration, edit it, and then re-run the
|
|
.Cm init
|
|
command with
|
|
.Fl -switch
|
|
enabled to activate the configuration.
|

|

.RS 4
