Ho un systemd-unit
sistema abilitato sul mio sistema. Il problema è che non si riavvia dopo un riavvio. Dipende da altri due servizi che sono entrambi avviati come previsto.
Il servizio è noto, abilitato e morto:
[centos@ansible-kube-4 ~]$ sudo systemctl status flanneld
flanneld.service - Flanneld overlay address etcd agent
Loaded: loaded (/usr/lib/systemd/system/flanneld.service; enabled)
Active: inactive (dead)
Il file dell'unità:
[centos@ansible-kube-4 ~]$ cat /usr/lib/systemd/system/flanneld.service
[Unit]
Description=Flanneld overlay address etcd agent
After=network.target
After=etcd.service

reenable
ho corretto qualcosa che non avevo fatto o che avevo sbagliato e che non riuscivo a vedere perché non stavo strizzando gli occhi abbastanza forte. Ad ogni modo, di due host identici su cui stavo configurando per rendere disponibile il mio servizio dopo il riavvio, uno ha funzionato e l'altro no fino a quando non l'ho fatto.
