Re: [Bug-tar] tar: '--overwrite' cannot be used with '--no-overwrite-dir'

Hi Somchai,

In fact, it did not.  At least, it didn't work the way you expected.  In
previous versions, when two conflicting options appeared, the last one
silently took effect.  That means that the above command was effectively
equivalent to

 gzip -cd /home/tmp/whatever.tgz | \
 tar --extract --numeric-owner --preserve-permissions \
     --overwrite --verbose -f - ./install

Since version 1.28, tar explicitly marks such usage as erroneous.
Please see this thread for details:
