Blocked status on initial deployment due to grub #40

Closed dashmage closed 2 weeks ago

dashmage commented 7 months ago

Deploying charm-sysconfig with ubuntu 22.04 results in the charm going into blocked status with the message: update-grub and reboot required. Changes in /etc/default/grub.d/90-sysconfig.cfg. But the 90-sysconfig.cfg file does not contain any specific config apart from some comments.

Upon SSH-ing into the unit, it looked like there was a difference between /etc/boot/grub.cfg and the grub config rendered using grub-mkconfig (which the charm uses to check whether there were any changes so it can notify for a reboot).

A similar problem had been resolved with the systemd conf file here: bug report, MP.

From the diff, we can see that there is somehow a difference in the way the root fs is being referenced (with the LABEL or with UUID).

given that sysconfig does not let you alter the root= kernel parameter, perhaps we should not include in the comparison
