Here's what happens upon installation of this package:

jurij@debian:~/linux$ sudo dpkg -i linux-base_2.6.32-8a~test1_all.deb 
Selecting previously deselected package linux-base.
(Reading database ... 64420 files and directories currently

Trying to install it again succeeds, I guess because it skips some 
already-asked debconf question, as it does not try to modify 
/etc/silo.conf the second time. The new silo.conf looks like this:

# root = /dev/sdb2
root = UUID=c6cd1add-df06-4bea-a511-76a0802d74b0

partition=1
default=Linux
read-only
timeout=100

image=/vmlinuz
	label=Linux
	initrd=/initrd.img

image=/vmlinuz.old
	label=LinuxOLD
	initrd=/initrd.img.old

which, quite predictably, is not understood by silo:

jurij@debian:~/linux$ sudo silo -f
Config file error: Syntax error near line 2 in file /etc/silo.conf
Error parsing silo config file /etc/silo.conf

I glanced through the SILO code and have not find any evidence that 
it supports device identification by UUID. Do you have any reason to 
believe that it should work, because I fail to see one.

Best regards,
