g> 1) what are the floppy drives that are designated with letter 'u'?
They're floppy devices that only run at specific capacities; they're
generally used for formatting disks and nothing else.

You need to add -h to halt or -r to reboot; see shutdown(8) for
details. I generally shut down with 'shutdown -h now -t3' or some
g> 3) how do I change run-level in debian? is there any utility or
The same way as with any other Linux: use the 'telinit' utility. So
'telinit 1' goes to single-user mode (same as 'shutdown' with no
flags), 'telinit 2' goes to a "standard" multi-user mode, etc.
<soapbox>Runlevels under Linux do not have a well-defined meaning,
although by convention 0 is shutdown, 1 is single-user, and 6 is
reboot. Debian doesn't have a particular runlevel for xdm vs. not
xdm; I've used systems where that runlevel has been 4, 5, and 6 (an
old Slackware box). Saying "I booted to runlevel 5" is *completely*
meaningless since the local admin can trivially change /etc/inittab to
do whatever he/she wants at each runlevel.</soapbox>
Normally in Debian runlevels 2, 3, 4, and 5 are all identical; you can
use the update-rc.d utility to change what runs when.
PS: Your "From:" line appears to be incorrect, in particular it has an
extra "z". Could you please fix it? Thanks...
