 Hello,
 I wanted to offer some supplemental information that I suspect is wider
 behavior for this same bug. On 5.2.1-RC, recognition of legacy filesystems
 appears to be broken, up to and including refusal of restore to recognize
 the -c switch:
 
 milo2.palas.com:/local/dump#uname -v
 FreeBSD 5.2.1-RC #0: Sat Jan 31 05:36:22 GMT 2004
 root at cypress.btc.adpatec.com:/usr/obj/usr/src/sys/GENERIC
 milo2.palas.com:/local/dump#file sunosdump
 sunosdump: dump format, 4.2 or 4.3 BSD without IDC
 milo2.palas.com:/local/dump#restore -rf sunosdump
 Tape is not a dump tape
 milo2.palas.com:/local/dump#restore -c -r -f sunosdump
 restore: illegal option -- c
 usage:  restore -i [-cdhmNuvy] [-b blocksize] [-f file] [-s fileno]
       restore -r [-cdNuvy] [-b blocksize] [-f file] [-s fileno]
       restore -R [-cdNuvy] [-b blocksize] [-f file] [-s fileno]
       restore -x [-cdhmNuvy] [-b blocksize] [-f file] [-s fileno] [file ...]
       restore -t [-cdhNuvy] [-b blocksize] [-f file] [-s fileno] [file ...]
 milo2.palas.com:/local/dump#restore -c
 restore: illegal option -- c
 usage:  restore -i [-cdhmNuvy] [-b blocksize] [-f file] [-s fileno]
       restore -r [-cdNuvy] [-b blocksize] [-f file] [-s fileno]
       restore -R [-cdNuvy] [-b blocksize] [-f file] [-s fileno]
       restore -x [-cdhmNuvy] [-b blocksize] [-f file] [-s fileno] [file ...]
       restore -t [-cdhNuvy] [-b blocksize] [-f file] [-s fileno] [file ...]

 I found that an eminently effective workaround was to just use the 4.10
 restore binary. I'm in the process of upgrading to 5.2.1-RELEASE, I'll post
 another update if I notice different behavior with it.
 
 I hope this information is helpful.
