Title:
  no reliable way to boot from iscsi root

Status in “open-iscsi” package in Ubuntu:
  New

Bug description:
  In order to boot from iscsi root via kernel parameters, the user would provide kernel parameters something like:
     iscsi_target_name=some-iscsi-target-name iscsi_target_port=3260 iscsi_target_ip=some.host root=LABEL=SOME_LABEL

  or potentially the same above but with root=UUID=SOME_UUID.

  The issue here is that this both LABEL and UUID could collide with a
  local filesystem.   Perhaps a previous install left a filesystem
  labeled "rootfs" that happened to match the filesystem of the
  iscsi_target_name and now using "root=LABEL=rootfs".  The same is
  possible with UUID.

  There needs to be some way to specify explicitly:
     root=iscsi_target_name=some-iscsi-target-name that would make the iscsi initialization code guaranteed to boot with the appropriate root device independent of whatever local filesystems might have.
