@nrwahl2 I was only able to update through the DRBD chapter. The Active/Active chapter requires installing gfs2, which we don't ship in RHEL 10 and therefore doesn't appear to be in any of the clones either. I haven't found a good solution to installing it anywhere, which makes me wonder what to do next. It's kind of a major portion of the CFS book.

* Update screenshots for Alma Linux 10.

* Fix the Installation Destination screenshot to be correct instead of a
  copy of the Manual Partitioning screenshot.

* Update instructions for ssh'ing since we can't do that as root by
  default anymore.

* Minor updates to command output.

Ref T910
* Add the rest of the "pcs status help" output.  This isn't super
  important, but we say we're going to show all the options, so we
  should do that.

* Update `pacemakerd --features` output.

No stonith devices and stonith-enabled is not false
error: Resource start-up disabled since no STONITH resources have been defined
error: Either configure some or disable STONITH with the stonith-enabled option
error: NOTE: Clusters with shared data need STONITH to ensure data integrity

I know these aren't the right error messages on main. This is what pcs on Alma Linux 10 produces, and I don't have a good sense of if it would all be one line or not. Also, the first message here probably needs to be changed to be current with the main branch too.

* GPG key location has changed.

* SELinux policy no longer seems to be relevant (and the semanage
  command doesn't work anyway).

* Fix a couple typos.

* Command output (especially pcs) has changed.

GFS2 is not available for RHEL 10, so it's not available for any of the
related operating systems either.  You've got to install it from source.
That's beyond what we want to explain in CFS.  However, I still want to
leave the GFS documentation here for people that do install from source,
or are following this document for an older release, or in case it
becomes available again.

I've updated the pcs commands and output as best I can, but I was unable
to run any of these commands on my test RHEL 10 system to verify.
