速读原著-GRUB_多系统引导(GRUB软件包版本选择和安装)

如前面所说,目前在在Unix类的操作系统中,大多是都有GRUB;GRUB几乎能引导所有X86架构的操作系统;功能之强,使用简单是GRUB最大的卖点;由于Windows 操作系统的先入为主的优势,使得大家对Windows的NTLOADER了解的比较多,而对开源社区的GRUB显得有点寞生,由此而带来使用上的“心理恐惧”;究其初学者对GRUB“恐惧”的主要原因还是对GRUB没有太多的了解和深入;无论是WINGRUB还是Linux版本的GRUB,最方便的还是对 GRUB命令行的操作;一谈到命令行(Command)的操作,可能初学者对此恐惧;其实没有什么难的,象北南这样低级的写手,还能操作得起来,您也应该能行;

linux文件树

以前有意找这方面的资料,今天突然发现在系统中就有 linux系统用man hier solaris用man  filesystem 其结果如下        /      This is the root directory.  This is where the whole tree starts.        /bin   This directory contains executable programs which are needed in sin-               gle user mode and to bring the system up or repair it.        /boot  Contains static files for the  boot  loader.   This  directory  only               holds  the  files which are needed during the boot process.  The map               installer and configuration files should go to /sbin and /etc.        /dev   Special or device files,  which  refer  to  physical  devices.   See               mknod(1).        /dos   If  both MS-DOS and Linux are run on one computer, this is a typical               place to mount a DOS file system.        /etc   Contains configuration files which are local to the  machine.   Some               larger  software  packages, like X11, can have their own subdirecto-               ries below /etc.  Site-wide configuration files may be  placed  here               or in /usr/etc.  Nevertheless, programs should always look for these               files in /etc and you may have links for these files to /usr/etc.        /etc/opt               Host-specific configuration files for add-on applications  installed               in /opt.        /etc/sgml               This  directory  contains  the  configuration files for SGML and XML               (optional).        /etc/skel               When a new user account is created, files from  this  directory  are               usually copied into the user’s home directory.        /etc/X11               Configuration files for the X11 window system (optional).        /home  On  machines  with  home  directories  for  users, these are usually               beneath this directory, directly or  not.   The  structure  of  this               directory depends on local administration decisions.        /lib   This directory should hold those shared libraries th
