Default Need to confirm re 'fstab', before rebooting my Squeeze

Well, I've rebooted and come out alive. So the Squeeze installer's
suggested GRUB destination, which I happily accepted, must have
been /dev/sdb. Lucky me. For next time, thanks for this alert!

One possible gotcha. When GRUB was installed where was it installed to?
If it's to /dev/sda you may have a little remedial work to do! This
caught me out a couple of times when I forgot to remove the USB stick at
that stage of the install.

Default Need to confirm re 'fstab', before rebooting my Squeeze

I have similar behaviour from a third disk, external USB,
that gets auto-mounted on /media. Its partitions aren't
named, and their order is messed up, so I just umount
them all and call a little script that remounts them else-
where on orderly named directories.

I didn't run into that. The installer correctly identified the root
partition, MBR etc. I only was burned by the fact it listed /dev/sdb1
as a cdrom device in fstab, but /dev/sdb1 was basically behaving like
one. So when a thumb was plugged in after the install had completed, it
would fail to auto mount on my desktop as expected. Suppose a udev rule
was confused. Mounting the device to a mount point by hand worked fine.

I may have alarmed you unduly and should have mentioned the behaviour I
experienced was with the netboot mini.iso. The netinst iso offered the
partitioned disk for GRUB installation. It's something to check,
however, rather than blindly accept.

If you used the mini.iso to install to a different device[1], then it
sounds like a bug. I can't think of any reason for the installer to
offer anything but the MBR of the device holding /boot as *default* for
installing grub.

[1] it's probably less known that the mini.iso can be used to install on
the same device used to boot the installer from, a handy feature if you
ask me.

Regards,
Andrei

The same thing came into my mind at the time but I moved on. Perhaps it
has been fixed in a daily build. I don't like reporting as bugs
something which I'm not sure about so I'll have a closer look at it
today. Which package would I report the bug against?

Definitely. Combining that with the loopback option in GRUB2 can be
interesting.

I think the recommended way is to just run installation-report after the
install.
