Did we must put the mounted partition '/' and '/boot' in the
same slice ?

Do the install again but do not make /boot a partition. 1Gb is more
than ample for / and /boot. Given that you have /tmp separately, 256Mb
would do. I, at least, never used that much even.

For all the talk of the 1024 cylinder problem, I have never encountered
it. I suspect that while it was true of older hardware, that it just
isn't the case any more. If this is a problem, then it is just the /
(root) partition that needs to start inside 1024 cylinders.
Apart from that, my opinion is that having swap = 2.5 * memory is still
a reasonable rule of thumb. You may never need it but a) it's a tiny
fraction of your disk and b) if you expand your memory in the future you
still have enough swap. You must have at least as much swap as physical
memory. With 1Gb I put in 4Gb of swap, just because it's peanuts
compared to a 200Gb disk. If I double my memory, I still have plenty of
/var depends on what this machine does. If it is a mailserver then 512M
is inadequate, for a home machine it's probably plenty. If you ever
need a crash dump from the kernel (and you may *never* need one, but if
you do...) then you need as much free disk space as you have physical
There was a recent thread about disk sizing (maybe a month ago?) so try
searching the archive.
I also found this useful when clarifying my thoughts about how to
partition a new disk:
