用preload大幅加速Gentoo

zhllg · 发表于 2008-3-19 13:05:20

如果我记得没错，ubuntu用的是upstart

现在已经在用baselayout2.0.0了，用的是openrc overlay里的，启动和关机，以及网络的启动，关闭速度有了很大的提高。
不过模块加载的设置位置变了，换成是在/etc/conf.d/modules中设置。刚开始的时候没注意，发现无线的WEP加密用不了了，lsmod发现ieee80211_crypt_wep没加载才注意到的。
rc的设置也换到了/etc/rc.conf中。
/etc/conf.d/net中的格式有变化，原来是config_eth0=(" "," ")的，现在换成config_eth0=" " 了。
兼容baselayout1的init脚本

因为我hda的DMA是通过hdparm来启动的，所以我在/etc/rc.conf中设置rc_need="hdparm"这样在并行启动的时候就会在boot level的时候先运行hdparm，从而在fsck的时候hda的DMA就打开了。否则容易跳出hda的DMA没有启动的警告

真是爽就一个字。

preload是一个很小的程序，通过preload这个小家伙，可以让你经常使用的程序启动速度更快。而且，小家伙是自适应的，它可以检测用户使用的程序，分析数据，预测用户可能会打开的程序，然后把需要的二进制代码或依赖的东西预先调入内存，这样就可以快速启动了。比如我们经常打开的firefox。

刚在网络里搜了一下，有疑问，安全性好不好？允许它往内存里写东西，溢出就麻烦，内存机制是如何？占用与收回内存是杂样？

read the fine source code

我编译出错，baselayout-2.0.0出错：

请把log贴全来，这样我是看不出来错在哪……

我用USE="bootstrap build" emerge -av baselayout安装的，失败，但是如果直接emrege baselayout可以成功，但是不能重启，关机了，说找不到／sbin／rc，重新安装了1.21.11.1才正常进入系统

acevery · 发表于 2008-3-20 00:58:24

你用的是哪里的ebuild？
我用的是openrc里的baselayout-2.0.0，它会装上openrc－9999做为依赖，没有问题的。
