I'll have a look at creating a small script that makes the above a bit easier, and documenting chroot operations a bit more.

See below.

I asked this because when I suspect about kotlin is not included in chroot enviroment, i tried to re-run them. The judgehost itself seems works after that. But I dont know the impact it will create. Can you give confirmation and more information about this ?

If you rerun dj_make_chroot, then you're creating the chroot from scratch, so any changes you made there before are lost. That also means that you'd have to rerun dj_make_ubuntu_java_chroot.

The judgedaemon itself does not modify the chroot at all, it only read-only bind mounts parts of it during each judging (see judge/chroot-start-stop.sh). Thus you can safely rebuild or change the chroot while the judgedaemon is not running.

Best,
Jaap
