User.tar.gz then decompresses config-origin.tar.gz, uses the content of config-origin.tar.gz as final system
The configuration file of system.
Again, start the last of initializtion script in initrd, decompress other necessary system files to newroot mesh
Record is used in combination umount to unload nonvolatile memory, finally executes chroot switch_root orders, system is switched
To newroot, after operating above, the root for being presented to the user the final system of operation is initrd's
Newroot catalogues.
After being switched to final system using orders such as switch_root, the non-of daily record is stored using mount order carries
Volatile memory is to/var/log catalogues.
Finally, it needs to increase the order that a user configuration preserves in the final system of making, such as names config-
Save, the function of this order are to beat compressed package to configuration file, and compressed package is named as config-user.tar.gz, and carry is non-easily
The property lost memory preserves config-user.tar.gz to nonvolatile memory, unloads nonvolatile memory.
Therefore, ramdisk performances can be improved using ramfs or tmpfs, and be not necessarily to extra occupancy Installed System Memory, ramfs
Committed memory size can be dynamically adjusted with tmpfs, memory headroom is equally wasted in advance rather than ramdisk.Solution system
While file security sex chromosome mosaicism, there is independent order that user is allowed to preserve configuration, improve the reliability of modification configuration file, use
Family arbitrary disposition, when causing confusion, it is easy to restore factory-said value, it is only necessary to which provide order is config-user.tar.gz deletions
It can complete, i.e., when user configuration causes confusion, it is only necessary to which the new configuration compressed file deleted on nonvolatile memory can
To leave configuration compressed file, which is exactly the compressed file of original configuration file, is easy to restore former in this way
Begin to configure.Moreover, there is the independent nonvolatile memory for preserving daily record, exception information is facilitated to track.
The method that user configuration is preserved under a kind of linux system provided by the present invention, configuration file are individually from root text
It is separated in part system, is individually packaged and is compressed, it is to be stored in non-volatile memories that other systems file, which becomes compressed package,
