consolefont: allow passing extra arguments to setfont

[Feasuro]

Summary

This change introduces support for an optional customflags variable in /etc/conf.d/consolefont, allowing users to pass additional arguments to the setfont command.

Motivation

Currently, the consolefont OpenRC service does not provide a way to customize the arguments passed to setfont. Users who need non-default behavior (for example, using the -d flag for double-size fonts) must modify /etc/init.d/consolefont directly.

Since this file is owned by the package, such changes are overwritten on upgrade, forcing users to rely on fragile workarounds such as patching via package manager hooks.

Proposed solution

Introduce a new optional variable:

customflags=""

This variable is sourced from /etc/conf.d/consolefont and appended to the setfont invocation:

setfont $customflags $consolefont $param -C $ttydev$x >/dev/null

Benefits

• Enables customization without modifying init scripts
• Preserves existing default behavior when unset
• Aligns with existing OpenRC patterns of exposing command arguments via /etc/conf.d/*
• Eliminates the need for downstream patching or hooks

Backward compatibility

No changes in behavior for existing users. If customflags is unset or empty, the command behaves exactly as before.

Example usage

To enable double-size console fonts:

consolefont="Lat2-Terminus16"
customflags="-d"
