This avoids the need for the activation block. The `dir` file is instead built directly in the installed profile.

# info.nix -- install texinfo and create `dir` file
|
|
|
|
# This is a helper for the GNU info documentation system. By default,
|
|
# the `info` command (and the Info subsystem within Emacs) gives easy
|
|
# access to the info files stored system-wide, but not info files in
|
|
# your ~/.nix-profile.
|
|
|
|
# Specifically, although info can then find files when you explicitly
|
|
# ask for them, it doesn't show them to you in the table of contents
|
|
# on startup. To do that requires a `dir` file. NixOS keeps the
|
|
# system-wide `dir` file up to date, but ignores files installed in
|
|
# user profiles.
|
|
|
|
# This module contains extra profile commands that generate the `dir`
|
|
# for your home profile. Then when you start info (and both `dir`
|
|
# files are in your $INFOPATH), it will *merge* the contents of the
|
|
# two files, showing you a unified table of contents for all packages.
|
|
# This is really nice.
