Are TrueCharts apps supposed to work? Not asking for guarantee, just if they are known not to because of breaking changes?
We do not offer support for DragonFish as this time, due to breaking-changes over at iX-Systems.
This is reflected by being unable to install new TrueCharts Apps.
I'm not aware of any breaking changes from Cobia to Dragonfish; however, I'd recommend you ask the TrueCharts community if they have any datapoints.
Removal of OpenEBS ZFS LocalPV, is quite a huge breaking change.
There is potentially an outstanding issue we just discovered yesterday where TrueCharts can consume all available space in /var/run during chart validation on adding new catalog.
This PR fixes a problem where we were still using temp dir when a new catalog was being added so we could validate it before adding it to the system. With the changes, now we use the apps dataset t...

It's affecting some users on Cobia and will be fixed in 23.10.2 and 24.04-RC1.
Not limited to TrueCharts, though we are the only one bug enough, that we're aware of, to trigger these issues.
THe fix is hugely appreciated though!
Is it possible to override the installation error...
Code:
Your system version is greater then specified maximum scale version for the app version
You can hack this, but it would just result in non-functional truecharts apps
What we did test was that memory pressure from services / Apps will indeed cause pressure in kernel and ARC to shrink dynamically to correspond to growing demand elsewhere. That was where the bulk of our testing resided and we feel confident that is working well. That plus a bunch of us have been running with 90%+ ARC on Cobia for months now and no issues, I think helps prove its working pretty decently so far :)
We can confirm this as well, we've done about a 2 years of experiment, Apps and VM's correctly cause shrinkage and memory pressure gets handled well. Even with "unlimited" ARC maximums.
