Steve,

I am willing to accept your reasoning.

I just want to mention that in times where other distributions introduce and 
advertise systemd,
any "transient" errors, which IMHO make upstart *look* unreliable in comparison,
should be really easy to analyse/track down at least, i.e "clever" diagnostics 
could be an advantage.

Again, I can only speculate how many guys gave up on using Ubuntu for
reasons like the current problem.


Maybe mentioning something in the manual for fstab is a start:

(Oneiric)
man fstab | grep -B 1 -A 2 UUID | head -5
              Instead of giving the device explicitly, one may indicate the 
(ext2 or xfs) filesystem that  is  to
              be  mounted by its UUID or volume label (cf.  e2label(8) or 
xfs_admin(8)), writing LABEL=<label> or
              UUID=<uuid>, e.g., `LABEL=Boot' or 
`UUID=3e6be9de-8139-11d1-9106-a43f08d823a6'.  This will make the
              system  more  robust:  adding  or  removing  a  SCSI  disk 
changes the disk device name but not the
              filesystem volume label.

This encourages the use of labels and/or UUIDs without the slightest
hint for possible drawbacks.


BTW,
is there an explicit reason why especially cryptsetup needs to intermediately 
hide the device which is typically already successfully unencrypted ?
Shouldn't that problem be fixed on a lower level before even the device *node* 
is created ?
I.e. is the crypt dm layer disclosing the "device data structure to be" too 
early to the kernel ?
Is udev listening on that device node creation ?
Maybe there could be improved udev rules ?
