Hi Whit,

which failed. apt-get always complained, that the kernel-image needs the 
new udev-package to upgrade - and udev itself needed the new

Yeah udev needs 2.6.27 or higher, so you have to upgrade the kernel first,
then reboot, then do the whole upgrade.

I have no idea what the plan for handling the upgrade is officially.
Maybe the release notes are supposed to offer some hint.

I've had problems like this several times, in several upgrades from an 
old stable to a new.  Sometimes X, sometimes udev, and once running out 
of disk space for the upgrade.  Usually I end up with an unusable 
system.  Not acceptable for a production system.

As a result I always copy the old stable system into separate 
partition(s), so that when an upgrade fails I can boot into the other 
copy and have
Because of these problems on a production machine, I've gradually 
learned to copy the old stable system into a separate partition, and 
then chroot to that to upgrade the copy while the old system is still 
running.

Of course, things go wrong this way, too.  Some packages want to 
fiddle with /proc during upgrade, and it isn't there.  I'm not at 
all sure whether to provide it.  Often things can be patched by booting 
to the incompletely updated new system and resuming the upgrade.  This 
does reduce the amount of time the productin system is in an unusable 
state.

I'd really like it if there were to be viable instructions in the 
release notes how to upgrade in a chroot, but I've never seen them.

Except during the reboot for the new kernel, of course.  I'm talking

If so, I'll probably copy the entire system (so I have a fallback just 
in case) and then upgrade as above.


 It worked - but - there is always some cruft that accumulates - so if you 
 have time, you might want to bkup your old etc and home - then move to a 
 new install - migrating configs one at a time. Some of my cruft dated 
 back to sarge...


 On the other hand - with a nvidia card and dual head monitors - kde4 is 
 amazing - I think we just left windoze in the rear view mirror..

Only one monitor, but I have nvidia on the motherboard.  Looking forward

I've done that with two production servers going from sarge to lenny on a Sunday night --- of course 
you have to restart services - a couple services were down for a few minutes while the con-figs were 
tweaked.


On servers, the right way is to set DNS ttl very low a week ahead of the move. Then set up a new 
system and move one service at a time. - Draw up a plan and a list ahead of time - save it for next 
time.


Desk top moves get more complicated..

I have been running the AMD64 testing stream on a box with a single core
AMD64 processor since March 2006. About the only thing which was missing
was a flash plugin or its equivalent but it did not bother me much. Now,
of course, there is more than one plugin. 

I have had no problem until recently when my GUI disappeared after an

the problem.
