Hi,
I have heard it is possible to change the kernel without reboots.
And I am not talking about UML.
Is it true? I could not find any documents on the web.
Regards,
Maciej

Are you referring to kexec?

Maybe your source was referring to modules. Modules can be replaced
while running, but that's it. The topic of replacing a running kernel
completely arises a few times a year. Check the list archive to see
what the problems are.

Eric Biederman has been working on 'kexec', which is a fast
reboot (Linux boots Linux). See
http://www.xmission.com/~ebiederm/files/kexec/
and
http://developer.osdl.org/%7Eandyp/kexec/
for some 2.5.[67]x versions. I'm trying to update it to
2.6.0-test3 and make it reboot successfully on my dual P4
machine. Currently it hangs during the reboot.

As well as kexec, maybe you want to look at the "two kernel monte".
This is what Scyld Beowulf uses to do single kernel image distribution.
Not sure what it's status is for 2.4, though. I'm only using it on 2.2.
