Ok, thank you.
Ok, after testing I can confirm that at least on my T5220 a separate partition for `/boot` is not needed. I'll try to check what my oldest UltraSPARC machines
make out if it.
Yes, but as you correctly mentioned, without a separate /boot partition, there
is always the risk that the blocklist method fails if the GRUB files are put
too far at the end of the / filesystem. We should maybe forward this question
Yeah, I just thought about figuring out by experiment if there are any
limits on the older UltraSPARC machines available to me.
One thing to note is, that per default GRUB uses `quiet` in the kernel command line, so depending on the speed of a machine and/or its disk drives, it might at
first look that nothing happens after GRUB has loaded kernel and initrd although the kernel is actually booting.
I *think* the GRUB parameters are set in finish-install, but
I am not sure.
I had a look, but this seems to be defined elsewhere. I traced it back
to the grub-ieee1275 package which creates `/etc/default/grub` in its
`postinst` script. This includes the var `GRUB_CMDLINE_LINUX_DEFAULT`
which defaults to "quiet" as per  =>  => .
Hm, I actually don't want to divert from the defaults - although maybe
the defaults sometimes might lead to irritations (no output for dozens
of seconds). Few people have that much patience. ;-)
