I’ve been tweaking my system’s startup time and came to a stand still with my investigation. Seemingly this service’s purpose is to log a successful grub bootup.
systemctl status grub-common.service
● grub-common.service - LSB: Record successful boot for GRUB
Loaded: loaded (/etc/init.d/grub-common; bad; vendor preset: enabled)
Active: active (exited) since Mon 2016-05-02 16:15:32 EDT; 48min ago
Docs: man:systemd-sysv-generator(8)
Process: 863 ExecStart=/etc/init.d/grub-common start (code=exited, status=0/
Tasks: 0 (limit: 512)
it’s at the tope of the “blame list”
systemd-analyze blame 12.628s grub-common.service
Can grub-common.service be safely disabled? I emphasize the word safely.
