S tim Trixiem nikako na zelenu granu....

Update na ovaj moj zadnji problem... Ukratko, pronašao sam zelenu granu pa ću probati to objasniti u par crtica jer se tiče systemda, a on i ja smo si još uvijek na "Vi". Kod friškog boota VM-a NFS bi se dizao prije nego je valjda odrađen DHCP handshake, NFS mount bi failao i Docker.service bi failao jer nisu ispunjeni neki preduvjeti:
Code:
sudo journalctl -b -u mnt-media.mount -u network-online.target -u remote-fs -u docker -u systemd-networkd-wait-online.service -u systemd-networkd --no-pager

Kao što sam već spomenuo, Docker bi se uredno dizao kada maknem sve iz override.conf. To očito nije radilo kako treba ili sam našao krivi/stari info. Ovo je stari setup:
Code:
sudo nano /etc/systemd/system/docker.service.d/override.conf
---
[Unit]
After=remote-fs.target
RequiresMountsFor=/mnt/media
Riješio sam problem (vjerojatno) na ispravniji način - kreiranjem servisa koji pinga NAS
prije nego se okine "network-online.target". U mom slučaju je 10.27.20.2 IP od NAS-a, ali možete pingati i ruter. Bitno je da ping prođe što bi značilo da je DHCP prošao i host je dobio svoj IP:
Code:
sudo nano /etc/systemd/system/media.service
---
[Unit]
DefaultDependencies=no
After=nss-lookup.target
Before=network-online.target
[Service]
ExecStart=sh -c 'while ! ping -c 1 10.27.20.2; do sleep 1; done'
Type=oneshot
RemainAfterExit=yes
[Install]
WantedBy=network-online.target
WantedBy=mnt-media.mount
Code:
sudo systemctl start media.service
sudo systemctl enable media.service
sudo systemctl status media.service

I za kraj sam pojednostavio override.conf za docker.service da čeka uspješno mountanje NFS sharea:
Code:
sudo nano /etc/systemd/system/docker.service.d/override.conf
---
[Unit]
Requires=mnt-media.mount
After=mnt-media.mount
Ovako sada izgleda cijeli proces kod bootanja:

Hebeno mi je trebalo vremena da pinpointam problem (bez AI-ja, jer nisam imao pojma što da ga pitam), pa ću s guštom okačiti i source za one 'koji žele znati više':
https://systemd.io/NETWORK_ONLINE/
Tu je bilo još gro reddit/docker forum postova gdje sam naučio bolje koristiti journalctl i što bi trebao pratiti. I pored svega toga još nisam spreman preći na desktop Linux
Mooožda ove godine!
