Append data to an existing gzip file, is it possible?

[jonny]

What i need is adding data to a gz file, without decompressing-appendingdata-recompressing, someone know if is it possible?

[jonny]

ops found:

gzip -c datafile >> archive.gz

gzip -l archive.gz doesn't give the correct datafile size (gives the size of the first chunk), but -d seems to work :D
