✓ -:- edit boot config

confirm boot config is correct and make changes (spelling errors, etc)


add `systemd.unit=rescue.target` to the end of the linux16 line


regenerate grub config with the following command:


`grub2-mkconfig -o /boot/grub2/grub.cfg`




To diagnose boot issues more easily, you decide to disable 'quiet boot' and 'graphical boot'

by removing 'quiet' and 'rhgb' from the kernel boot parameters. How would you accomplish

this so it's persistent?


✓ -:- Edit the 'GRUB_CMDLINE_LINUX' line in '/etc/default/grub' then regenerate the

bootloader config using 'grub2-mkconfig -o /boot/grub2/grub.cfg'.




Under normal circumstances, what is systemd's PID (Process ID)?


✓ -:- PID 1 - because it's the very first binary called by the kernel at boot, and is

responsible for starting up all other processes.




Which rescue parameter would you pass to the kernel from the grub2 menu if your system

was failing to boot because a filesystem check was failing?


✓ -:- systemd.unit=emergency.target

Booting to the emergency target state drops to a rescue shell after the 'root' filesystem has

been mounted readonly, but BEFORE other FS checks are carried out. Although you could

do the same with 'rd.break' it would require considerably more effort.




You are a member of a team of admins who are responsible for a critical system. This

system has two different web servers installed: The first (Nginx) is used to serve content,

the other (httpd) is installed only to satisfy dependencies and should never be started as it

causes a conflict. What command could you run to ensure that 'httpd' is never accidentally

started or enabled by another admin?


✓ -:- systemctl mask httpd




You're having a bad day and accidentally delete the 'initramfs' file in /boot that matches

your current kernel. Which command would you run to recover from this?


✓ -:- dracut




You've just made a configuration change to the 'SSHD' service and want to daemon to

reload it's configuration without disconnecting anyone. How could you accomplish this?


✓ -:- systemctl reload sshd.service




persistent hostname change with systemd
