Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, below in conjunction with specific embodiment, and reference
Accompanying drawing, the present invention is described in more detail.
It is the one of the method that same subregion installs multiple operating systems in storage medium provided by the invention referring to the drawings 1
The flow chart of individual embodiment.
Methods described comprises the steps：
Step 101：The read-only image file system of compression that operating system nucleus to be installed is used（Such as
squashfs）, the guidable compression kernel of operating system（Such as vmlinuz）And operating system root file system（Such as
initrd）It is packaged as the image format file of bootstrap support（Such as loopback）；
Step 102：By BIOS, MBR（MBR）, bootstrap（Such as grub）, the bootstrap supports
The driving of image format file and boot configuration file（Such as grub.cfg）It is uniquely right to be packaged as the operating system to be installed
The bootstrap bag answered；
Step 103：Replicate read-only image file corresponding to the operating system to be installed, the bootstrap support reflect
As formatted file（Such as loopback）And the bootstrap bag is to same subregion to be installed；
Step 104：The bootstrap bag is installed to realize guiding and startup to the read-only image file of operating system.
Further, the boot configuration file（Such as grub.cfg）In include each operating system to be installed
Boot entry.
From the above, it can be seen that the installation of same subregion is more in the storage medium provided by using one embodiment of the invention
The method of individual operating system, the installation of multiple operating systems, and the installation method can be realized in same subregion on a storage medium
It is simple to operation, it greatly simplify the installation process of operating system.
Union file system（Unionfs）It is the union file system of a stacking-type, multiple catalogues (can be also named point
Branch) content merges, and the physical location of catalogue is separated.Unionfs allows read-only and read-write catalogue and deposited, just
It is to say to delete and increase content simultaneously.
The place of Unionfs applications is a lot, for example merges the master catalogue of different file in multiple disk partition, or
Several CD CDs are merged into a unified CD-disc catalogs (filing).In addition, there is copy-on-write（copy-on-write）Work(
Energy Unionfs can merge read-only and read-write file system, and the virtual upper modification for allowing read-only file system can
To be saved among writeable file system.In class Unix operating systems, typically all there is union file system interface.
It is the another of the method that same subregion installs multiple operating systems in storage medium provided by the invention referring to the drawings 2
The flow chart of one embodiment.
Methods described comprises the steps：
Step 201：Obtain the catalogue of each operation system image storage medium institute to be installed carry（Such as/bolod）；
Step 202：In the catalogue, unique read-write file is created corresponding to each operating system to be installed
（Such as rootsave）；
Step 203：By calling union file system（Such as Unionfs）Interface is by the read-write file（Such as
rootsave）Corresponding operating system foundation to be installed merges, and using the read-only image file system of high compression rate
Controlling is made for read-only image file corresponding to the operating system to be installed.
Step 204：Delete bootstrap in the read-only image file system of compression that the operating system nucleus uses and
The data relevant with storage feature, and delete carry relevant with storage feature in fstab files.
Step 205：The read-only image file system of compression that operating system nucleus to be installed is used（Such as
squashfs）, the guidable compression kernel of operating system（Such as vmlinuz）And operating system root file system（Such as
initrd）It is packaged as the image format file of bootstrap support（Such as loopback）；
Step 206：By BIOS, MBR（MBR）, bootstrap（Such as grub）, the bootstrap supports
The driving of image format file and boot configuration file（Such as grub.cfg）It is uniquely right to be packaged as the operating system to be installed
The bootstrap bag answered；
Step 207：Replicate read-only image file corresponding to the operating system to be installed, the bootstrap support reflect
As formatted file（Such as loopback）And the bootstrap bag is to same subregion to be installed；
Step 208：The bootstrap bag is installed to realize guiding and startup to the read-only image file of operating system.
Further, the catalogue of each operation system image storage medium institute to be installed carry is same catalogue（Example
Such as/bolod）.
From the above, it can be seen that same subregion is installed in the storage medium provided by using another embodiment of the present invention
The method of multiple operating systems, the installation of multiple operating systems, and the installation side can be realized in same subregion on a storage medium
Method is simple to operation, greatly simplify the installation process of operating system.
Referring to the drawings 3, the method that multiple operating systems are installed for same subregion in storage medium provided by the invention is
The schematic flow sheet of one embodiment started of uniting.
The process of guiding and startup of the installation bootstrap bag to the read-only image file of operating system includes：
Step 301：Run the bootstrap bag；
Step 302：BIOS detects hardware information；
Step 303：Load the MBR（MBR）And run；
Step 304：Read the boot configuration file（Such as grub.cfg）And run the bootstrap（Such as
grub）；
Step 305：Selection operation system startup item；
Step 306：Run the driving for the image format file that the bootstrap is supported；
Step 307：The image format file that bootstrap described in carry is supported（Such as loopback）；
Step 308：Load the guidable compression kernel of the selected operating system（Such as vmlinuz）And operation system
System root file system（Such as initrd）；
Step 309：The read-only image file system of compression that selected operating system nucleus described in carry uses（Such as
squashfs）；
Step 310：Into the selected operating system.
From the above, it can be seen that after the necessary file for needing operating system to be mounted is copied into subregion to be installed,
The guiding provided by using above-described embodiment and the method for start-up operation system, you can start as needed any mounted
Operating system is simple and convenient quick.
