/dev is a pseudo file system created by udev. Under ordinary conditions,
no data in it persists across reboots. I suspect that udev does not create
a /dev/by-label directory unless it detects a disk partition with a label
during boot.
Perhaps none of Bob's partitions are labeled? A label is optional, both for
mkswap and mke2fs. And if the partitioning/formatting is done by the Debian
installer, there may not be any labels. A label can be added after the fact
with e2label, or an inactive swap partition can be reformatted by mkswap with
a label specified. blkid will list the label, if there is one.
Caution: reformatting a swap partition with mkswap will change the
uuid unless the existing one is explicitly re-specified during formatting.
