On disk, files seem to be intact. The kernel/world is from early on Feb 2 (~6am GMT). [Perhaps this has been fixed since then, but I didn't see any updates that screamed: NFS update!, just a couple VM updates.] GDB is free software and you are welcome to distribute copies of it under certain conditions; type "show copying" to see the conditions.
