And now (I'm sure this thread was here before ;-) again, just to annoy you
all: :-)

I'd like to see a new harddisk device naming scheme which allowes me
to disconnect one of my SCSI harddisks without having to rename _all_
my mounts on disks behind this one just because Linux has a
br********ed way to dynamically allocate device nodes to harddrives.

What is wrong with

/dev/sdaa0 for first primary partition on SCSI ID 0 on the first controller
/dev/sdbc5 for the first secondary partition on ID 3 on the 2nd controller

in this case I could remove my ID '3' harddisk (hint: There are drives with
removeable medias which sometimes have no media inside at boot-time...)
without silently renaming /dev/sdd (on ID4) to /dev/sdc.

IMVVHO this is an _ugly_ side effect which reminds me of the bad DOS
habit to re-shuffle all drive letters at boot time.

We could even make this in a compatible and decent way: Just keep the
old sd<x> stuff and create them dynamic at boot time as links onto the
device nodes for the drives (/dev/sdaa0 - /dev/sdhh7 for seven SCSI
controllers e.g.).

I'd really like to see this. :-)
