Subject: gentoo: vconsole-setup support.
X-Git-Tag: v11~121
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=9841e8e3d305e6f4173c9aedbe8d57adfe10d145

gentoo: vconsole-setup support.

This patch is a bit bigger than expected since Gentoo being
non-standard in some places.

 1. it is installing binaries at /usr/bin instead of /bin.

 2. it is using CamelCase names for consolefonts.

 3. /etc/rc.conf:unicode=(yes|no) just forbids loadkeys and setfont
    "-u" options, but do not disable the actual kernel default_utf8
    from vt module.
