All,
According to "Setting Up Unix - Seventh Edition", by Haley and Ritchie:
The best way to convert file systems from 6th edition (V6) to 7th
edition (V7) format is to use tar(1). However, a special version of tar
must be prepared to run on V6.
The document goes on to describe a reasonable method to make v6tar on v7
and copy the binary over to the v6 system. I successfully built the
v6tar binary, which will execute in the v7 environment. I then moved it
over to the v6 system and did a byte compare on the file using od to
dump the octal bytes and then comparing them to the v7 version. The
match was perfect.
The problem is this, when I attempt to execute the v6tar binary on the
v6 system (it works in v7) it errors out:
v6tar
v6tar: too large
on the v7 system, it works:
v6tar
tar: usage tar -{txru}[cvfblm] [tapefile] [blocksize] file1 file2...
I don't think the binary is too large, is is only 18148 bytes.
ls -l v6tar
-rwxrwxrwx 1 root 18148 Oct 10 14:09 v6tar
Help. First, what does too large mean? Second, does this sound familiar
to anyone? etc.
Thanks,
Will
