Configuration
Configuration on Plan 9 is largely the same as other platforms. This section defines platform-specific differences.
File paths
Configuration file paths have been slightly modified to fit into the Plan 9 file system hierarchy:
Per-user configuration:
$home/lib/hgrc
Per-system configuration:
/lib/mercurial/hgrc
/lib/mercurial/hgrc.d/*.rc
Per-installation configuration:
<install-root>/lib/mercurial/hgrc
<install-root>/lib/mercurial/hgrc.d/*.rc
For more detail, see hg help config.
Other differences
By default, installations will have the FactotumExtension enabled; this extension permits factotum(4) to act as an authentication agent for HTTP repositories. Additionally, an ExtdiffExtension command named 9diff is enabled which generates diff(1) compatible output suitable for use with the plumber(4).
Commit messages are plumbed using E if no editor is defined; users must update the plumbed file to continue, otherwise the hg process must be interrupted. This change was primarily made to reduce confusion as vi is the MIPS instruction simulator on Plan 9 platforms.
