Long ago, I swear it was just tar but something broke on some host. My
vague recollection
is very large user ids in a Mac networked environment. But the ustar format
allows 8 octets
for user ids.

That may not have tripped the switch to pax except that pax is the POSIX
name of the
command.

Looking for the RHEL 8 release notes about this, I found

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/considerations_in_adopting_rhel_8/index


which indicates it moved to the "CodeReady Linux Builder repository" along
with a
number of other packages. That is in the PowerTools repo for CentOS.

Hopefully it works. Jeff will let us know.
