i want to start playing with kexec and i've noticed some confusing (and possibly erroneous) documentation. first, i see that, when you configure a kernel you're about to build, you can make it relocatable. with kexec, i'm assuming that that only makes a difference with the kernel you are going to kexec *to* -- whether or not the current kernel is relocatable is not relevant, is that right? next, from the man page for "kexec": "Note: Compressed kernel images such as bzImage are not supported by kexec. Use the uncompressed vmlinux." excuse me? from what i can read, you certainly can load a bzImage-format file, since the "-t" option to kexec supports that, as you can see from "kexec --help". finally, i found the following online example: Thanks a lot topdog.. finnaly I got able to switch another kernel..I used below command kexec -l -t bzImage --command-line="ro root=/dev/VolGroup00/LogVol00" \ --initrd="/boot/initrd-2.6.24.3-custom_test.img" /boot/vmlinuz-2.6.24.3-custom_test that doesn't seem to make sense, as the writer is using "-t bzImage" while passing a regular vmlinuz-format kernel. or am i misunderstanding this? thanks. rday -- ======================================================================== Robert P.
