Description Martin Kammerhofer 2001-02-11 22:50:01 UTC 
Tar is supposed to preserve owner/group when invoked as root.
This does not work for extracted symlinks.

Note: FreeBSD's cpio(1) from the base system and gtar from the ports
collection can do that.

How-To-Repeat: 
As root do:
# ln -sf /1/2/3 slink
# chown -h nobody:nogroup slink
# ls -l slink
lrwxr-xr-x   1 nobody  nogroup  -      6 11 Feb 23:35 slink@ -> /1/2/3
# tar cf slink.tar slink
# rm -f slink
# tar xf slink.tar
# ls -l slink
lrwxr-xr-x   1 root    wheel    -      6 11 Feb 23:35 slink@ -> /1/2/3

More modern tar which was just imported into the 5.0-CURRENT doen't have this 
problem. The problem will be fully resolved when tar upgrade is MFCed in 
about 1 month.
