Hello,

you can exclude some files from being saved to the snapshot. From "man
live-snapshot":

FILES
          /etc/live-snapshot.list

      This optional file, if present changes the behaviour of live-snapshot,
      only files and directories listed there are included (integrally) in
      the snapshot. It works only for cpio and whole partition targets.

          /etc/live-snapshot.exclude_list

      This optional file, if present will filter the files that will be saved
      by live-snapshot removing (as in "grep -F -v") all filenames that will
      be matched by strings listed in it. It works for cpio, whole partition
      and squashfs snapshot types only; it is pretty useful for filtering
      temporary files and disk caches.

For this case you could use the file /etc/live-snapshot.exclude_list
and exclude the file where wicd saves the known network interfaces, so
each time you restart in a different computer, wicd starts with no
known interfaces and behaves correctly.

I'm not sure for wicd and I don't use full persistence, but excluding
the files you said in /etc/udev/rules.d/ and also
/etc/network/interfaces could be what you want.

Have fun,
