 Unfortunately I did have to reboot relatively recently and will probably
have to do it again soon due to the serious security problems found in the
kernel.

 As long as it seems reasonable, yes.

 I did want to set things up to use kexec, but have never actually done it.
It still seems like it could be nice to use it and it's also supposed to be
much simpler to set up now than when I looked at it many years ago, so
perhaps it's worth looking into again.

 But for now I'll just reboot my machines manually soon to deal with the
"dirty pipe".
