Sorry for rising this again. I found in CVS the following:


CVS log for src/gnu/usr.bin/tar/create.c
...
Support 21-bit minor numbers.  Avoid wasting a byte in their octal
representation by generating the same format as tar-1.13 (use a single
space as the terminator for 7-digit octal numbers).  This is POSIX.1
conformant (2-byte terminators are just a bug or historical wart in
old versions of gnu tar).  All devices created by `MAKEDEV all' except
rsa0.ctl can now be handled by tar(1).


Perhaps this 21-bit size should be indicated too?

Best regards,
V. Tchoukharev
