Debian stable is running kernel 6.1 right now, I tried to port mars to 6.1 but failed immidiately.
Then I tried to port mars to kernel 5.10 (to run on debian oldstable), and failed again - so many changes to kernel_setsockopt I am not familiar with, but I am still trying :)
So we stuck to 4.9 and 5.4 kernel ? What OS would you recommend for 5.4 ?
Why: there is no alternative to mars, DRBD geo replication is fake without their proprietary DRDB Proxy with unknown price lol.
