是的，但并非没有任何努力。在Linux上有2种不同的休眠方式（挂起至磁盘）：
- swswap，它包含在内核中
- tuxonice（以前称为suspend2），不是。
Tuxonice可以作为内核的补丁程序使用，可以让您将挂起的映像写入普通文件。
来自维基百科：
TuxOnIce (formerly known as Suspend2) is an implementation of the suspend-to-disk (or hibernate) feature which is available as patches for the 2.6 Linux kernel. It was formerly known as 'swsusp'. During the 2.5 kernel era, Pavel Machek forked the original out-of-tree version of swsusp (then at approximately beta 10) and got it merged into the vanilla kernel, while development continued in the swsusp/Suspend2/TuxOnIce line. TuxOnIce includes support for SMP, highmem and preemption. Its major advantages over swsusp are:
* It has an extensible architecture that allows for arbitrary transformations on the image and arbitrary backends for writing the image;
* It prepares the image and allocates storage prior to doing any storage and accounts for memory and storage usage very carefully, thereby becoming more reliable;
* Its current modules for writing the image have been designed for speed, combining asynchronous I/O, multithreading and readahead with LZF compression in its default configuration to read and write the image as fast as hardware is able;
* It has an active community supporting it via a wiki, mailing lists and irc channel (see the TuxOnIce website);
* It is more flexible and configurable (via a /sys/power/tuxonice interface);
* Whereas the current swsusp (and uswsusp) implementations support writing the image to one swap device only, TuxOnIce supports multiple devices in any combination of swap files and swap partitions. It can also write the image to an ordinary file, thereby avoiding potential race issues in freeing memory when preparing to suspend.
* It supports encryption by various methods;
* It can store a full image of memory (resulting in a more responsive system post-resume), while uswsusp and swsusp write at most half the amount of RAM.
由于默认内核中未包含该内核，因此很遗憾，您必须选择可用于Jaunty 的 内核补丁并自行编译内核。
有一些扩展指令在这里，但你可能想尝试罗伯特的建议，徘徊在这条路上之前，除非你是一个老的手在滚动自己的内核映像。
