[solved] Jail Java Runtime Environment

[cobrakiller58]

Updating a jail to the latest version and ran into an error

Code:

 Installing linux_base-c7-7.9.2009...
Cannot install package: kernel missing 64-bit Linux support
pkg: PRE-INSTALL script failed

after some searching is adding a tunable to TrueNAS Core still the solution to get Java running in a jail?

Code:

System->Tunables -> Add Tunable(s)
variable: linux_enable
value: YES
Type: rc.conf

The answer is yes

What for do you need Linux compatibility to run Java? pkg install openjdk(8|11|17|18) and you are all set.

17 would not install without linux compatibility

Code:

root@proxy:~ # freebsd-version
13.1-RELEASE
root@proxy:~ # pkg install openjdk17
[...]
root@proxy:~ # java -version
openjdk version "17.0.4" 2022-07-19
OpenJDK Runtime Environment (build 17.0.4+8-1)
OpenJDK 64-Bit Server VM (build 17.0.4+8-1, mixed mode, sharing)

Jail on my TrueNAS - no Linux compatibility whatsoever ...
