Of couse, I am dont extract from base.txz /etc and /var itself, only

Actual command is:
tar xf - --exclude ./boot/device.hints ./COPYRIGHT boot dev media mnt proc tmp
bin lib libexec rescue sbin usr
because tar don't allow include/exclude and var in base.txz also
contains var/log/sendmail.st, var/crash/minfree,

Thanks, I try this.
