Problems unpacking sets with ftp -o

[Louis Guillaume <louis%zabrico.com@localhost>]

Hello!

My longtime update method for netbsd systems (since NetBSD 1.6 or so) 
summarized...

1. Retrieve/unpack the kernel
  # cd /
  # ftp -o "|pax -zrvpe" 
http://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-9/latest/amd64/binary/sets/kern-XEN3_DOMU.tar.xz

2. reboot

3. Retrieve unpack the sets

  # for i in base comp games modules man misc text ;do
  > ftp -o "|pax -zrvpe" 
http://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-9/latest/amd64/binary/sets/${i}.tar.xz
  > done

4. Get the etc.tar.xz and run etcupdate on it.
  # cd /usr/INSTALL
  # ftp 
http://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-9/latest/amd64/binary/sets/etc.tar.xz
  # etcupdate -d / -s /usr/INSTALL/etc.tgz

5. Reboot.


But this doesn't work as of recent. Step 3 breaks. It seems that since 
moving from .tgz to .tar.xz archives I have this problem.

The kernel works fine, but for the sets, I get the following problem 
after a while...

./usr/share/locale/zh_CN.GB18030
./usr/share/locale/zh_CN.GB18030/LC_CTYPEgzip: Unexpected end of input

ATTENTION! pax archive volume change required.

As if the pipe to pax is misbehaving.

Any thoughts on this? My workaround is to download everything to 
/usr/INSTALL first. Then pax works fine in the loop.
