pmount-hal not using labels on encrypted filesystems

[Aidan Gauland <aidalgol@no8wireless.co.nz>]

When I mount a filesystem on an encrypted partition with pmount-hal, it
just mounts it on /media/usbdisk instead of using the filesystem's label
to name the mount point, as it does with unencrypted filesystems.

For example,

$ pmount-hal /dev/sdb1
Enter passphrase for /dev/sdb1: 
/dev/mapper/_dev_sdb1 on /media/usbdisk type ext4 (rw,noexec,nosuid,nodev,errors=remount-ro)

But I want the mount point to be named after the label of the (encrypted) filesystem
on /dev/sdb1, in this case, "Gauland_HDD."

How can I fix this?  Given that HAL is deprecated, I suspect there is
some other tool that serves the same purpose as pmount-hal that I should
be using instead.
