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

POSIX.2 style variable references. For example, a variable

{var}`parameter` may be referenced as

`$parameter` or `''${parameter}`. A

|
||
If the script block produces any observable side effect, such

as writing or deleting files, then it

*must* be placed after the special

`writeBoundary` script block. Prior to the

does not modify, the state of the system and exits if an

A script block should respect the {var}`DRY_RUN` variable. If it is set

is provided for activation script blocks. It is used as follows:

{command}`run {command}`

: Runs the given command on live run, otherwise prints the command to

standard output.

{command}`run --silence {command}`
|
||
: Runs the given command on live run and sends its standard and error
|
||
output to {file}`/dev/null`, otherwise prints the command to standard
|
||
output.
|
||
|
||
The `--quiet` and `--silence` flags are mutually exclusive.
|
||
|
||
A script block should also respect the {var}`VERBOSE` variable, and if
|

set print information on standard out that may be useful for debugging
|
||
any issue that may arise. The variable {var}`VERBOSE_ARG` is set to
|
