** Description changed:
- I started up a precise/netboot install using debian-
- installer_20101020ubuntu136 and disk-detect/multipath/enable=true and
- found that multipath support didn't appear to be working. That is to
- say, both paths appeared as separate disks in the installer, and no
- device-mapper devices were instantiated.
+ [SRU Justification]
+ multipath no workie, see the original description
+
+ [Regression Potential]
+ In theory, multipath suddenly working again could be surprising to people who have worked around it being broken for so long. This seems unlikely.
+
+ [Test case]
+ Boot a d-i install with disk-detect/multipath/enable=true, and once the udebs
+ have been installed, drop to a shell and try to run 'multipath' to see if it explodes with a symbol resolution error. Ideally it won't.

+ [Original report]

That is to say, both paths appeared as separate disks in the installer, and no device-mapper devices were instantiated.
I dropped to a shell and discovered that /sbin/multipath fails to run:
BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash)
Enter 'help' for a list of built-in commands.
~ # multipath
multipath: symbol lookup error: /lib/libmultipath.so.0: undefined symbol: dlopen
Note: this also seems to be the case in oneiric, though oneiric also has
a bug where it does not appear to have the dm-multipath module available
at install time.
