今天在看todotxt的ebuild的时候发现，
[axlrose@ibmgentoo .bash_completion.d] $ sudo eselect bashcomp list|grep todo
 [37]  todotxt
[axlrose@ibmgentoo .bash_completion.d] $ sudo eselect bashcomp enable todotxt

以前用eselect bashcomp的时候没注意，原来是这么回事，在 ~/.bash_completion.d 目录下做ln -s ，看来此招跟rc-update类似

其二是在使用todotxt的ebuild的时候，发现这个overlay没在官网指点的里面，根据提示原来就这样就搞定了，试了一下里然行，因为这个overlay用的是git，速度飞快，下载速度看了一下，105K/s 我的是 1M的电信ADSL，知足了

1. Install app-portage/laymanif you haven’t already.

2. Edit /etc/layman/layman.cfg and add the following URL to the “overlays:” section: http://github.com/joshuar/ephemeral-gentoo-overlay/tree/master%2Foverlay.xml?raw=true

3. Run: layman -L.

4. Run: layman -a ephemeral.

5. You should now be able to install packages from the overlay.
