Indeed.

No sdb1 is mentioned, despite it apparently being recognised by the kernel when plugged in (from the last line of the `grep  kernel /var/log/messages` output in my previous post).

  $ ls -l /dev/disk/* | grep sdb
  lrwxrwxrwx 1 root root  9 Aug 29 14:51 usb-Generic-_Card_Reader_20060413092100000-0:0 -> ../../sdb
  lrwxrwxrwx 1 root root  9 Aug 29 14:51 pci-0000:00:12.2-usb-0:1:1.0-scsi-0:0:0:0 -> ../../sdb
  $ 

The same command, grepping sda, shows much longer output, with symlinks to all the partitions 

Is it udev that's responsible for populating the dev nodes?
(is that the right terminology?)

How do I force it to reconstruct the partition table? Surely one should expect to be able to format or partition a removable drive and have the dev nodes created without the necessity of rebooting?

It's the normal one:

  $ equery belongs `which mount`
   * Searching for /bin/mount ...
  sys-apps/util-linux-2.28.2 (/bin/mount)
  $
