Hi,<br>
I think you misread that RHEL 8 page. I had already looked there, but looked again tonight. Pax is only listed once on the whole page, and it's under this heading:<br>
A.4. Removed packages<br>
The following packages are part of RHEL 7 but are not distributed with RHEL 8:<br>
<br>
The "Homepage of Pax" looks a little stale. ---> <a href="https://pax.grsecurity.net/" target="_blank" rel="noreferrer">

Does RTEMS understand the standard tar format? If PAX format is needed does your<br>
<br>
tar accept `--posix` or `--format pax`. I am happy for a change like this but it<br>
<br>
may only work on FreeBSD ;)<br>
<br>
<br>
<br>
<br>
<br>
Long ago, I swear it was just tar but something broke on some host. My vague recollection<br>
is very large user ids in a Mac networked environment. But the ustar format allows 8 octets<br>
for user ids.<br>
<br>
<br>
<br>
<a href="https://pubs.opengroup.org/onlinepubs/9699919799/utilities/pax.html#tag_20_92_13_06" target="_blank" rel="noreferrer">https://pubs.opengroup.org/onlinepubs/9699919799/utilities/pax.html#tag_20_92_13_06</a> <br>
<br>
<br>
<br>
That may not have tripped the switch to pax except that pax is the POSIX name of the<br>
<br>
<br>
command.<br>
<br>
<br>
<br>
Looking for the RHEL 8 release notes about this, I found <br>
<br>
<br>
<br>
<a href="https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/considerations_in_adopting_rhel_8/index" target="_blank" rel="noreferrer">https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/considerations_in_adopting_rhel_8/index</a> <br>
<br>
<br>
<br>
which indicates it moved to the "CodeReady Linux Builder repository" along with a <br>
<br>
<br>
number of other packages. That is in the PowerTools repo for CentOS.<br>
<br>
<br>
<br>

<br>
<br>
<br>
Hopefully it works. Jeff will let us know.<br>
