currently sysinst calls `pax -zrpe -O -f filename.tgz' to extract
sets.

if a file system fills, this results in repeated "No space left
on device" errors until the user hits ^C (and sysinst bombs) or waits
for it to finish - neither of which are the right thing.

now that pax-is-tar, is there any reason we can't use the tar variant
in sysinst with the -e option (abort on first error)?

pax treats its equivalent option -E differently, and it only limits
the number of _read_ faults.

thoughts?
