[SOLVED] - rpmbuild Sources can they use 'xz' format

[warron.french]

Can I create a tarball using the xz algorithm of compression and reference it in the tag Source0?

For example, can I create a tarball with the name of firefox-60.7.2.tar.xz, using the tar options of cvJf and then provide that same name in the tag as:

Source0: firefox-60.7.2.tar.xz

Is there an rpmbuild convention against using various compression algorithms?

Yes.

Awesome, thank you.

I am writing a script to build a Custom RPM for installing any Firefox version into a different place than normal, but still using the
firefox-version.tar.bz2 file off of mozilla.org.

For anyone else ever reading this...
Yes, it absolutely worked, you can use tar.xz files as a Source and reference it in your SPEC file.
