First, thanks for your pioneering work on using the Red Pitaya as a Skimmer
SDR.

Yes, that is exactly what I see when I log in.  As far as I can tell, this
is the most recent image available that runs Pavel Demin's SDR receivers.
I plowed through a bunch of posts in the Red Pitaya forums, and it seems
that newer builds of the OS still have open issues that break his
applications.  I sent an email to Pavel Demin asking about plans for a
v0.97 image, but he did not respond.  I tried using the Version 0.97 image
that came pre-installed with the new Red Pitaya STEM 125-14 Stater Kit, but
the v.94 SDR Receiver in the Red Pitaya MarketPlace does not run on v.97 OS.

This version currently running here DOES allow a persistent password change

Only if you maintain power to the Red Pitaya.  If you power cycle the SDR,
it resets itself to root/root every time and sets the date back to 1970.
That's two reasons I want to go to v0.97, which apparently supports
persistent passwords, and setting its clock automatically.

If you have this working OK on v0.95 already, please share.

Do you have the Ubuntu Linux version that is required to rebuild his
SDR-Receiver from the source?

On Windows, I managed to fix some bugs in the HermesIntf.dll that caused
gibberish to appear in the Skimmer drop-down list and SkimSrv.ini file when
using CWSL_Tee. It now returns a proper skimmer name that follows the RP
naming convention, e.g. "CWSL_Tee on RP-F050EB v25" but have not sent the
updated source to K3IT yet.

73,
