[systemd-devel] Why is my reboot.target disabled?

[Ferenc Wágner]

Hi,

Please help me understand this phenomenon (systemd 252):

$ systemctl status ctrl-alt-del.target
○ reboot.target - System Reboot
     Loaded: loaded (/lib/systemd/system/reboot.target; disabled; preset: enabled)
     Active: inactive (dead)
       Docs: man:systemd.special(7)

$ ls -l /{etc,run}/systemd/system | fgrep reboot

$ ls -l /lib/systemd/system | fgrep reboot
lrwxrwxrwx 1 root root   13 febr  28 12.15 ctrl-alt-del.target -> reboot.target
-rw-r--r-- 1 root root  443 febr   1 18.20 plymouth-reboot.service
-rw-r--r-- 1 root root  598 febr  16 19.10 reboot.target
drwxr-xr-x 2 root root 4096 ápr   22 22.15 reboot.target.wants
lrwxrwxrwx 1 root root   13 febr  28 12.15 runlevel6.target -> reboot.target
-rw-r--r-- 1 root root  568 febr  16 19.10 systemd-reboot.service

What does it mean that reboot.target is disabled?  And why is it?

# systemctl enable reboot.target
Created symlink /etc/systemd/system/ctrl-alt-del.target → /lib/systemd/system/reboot.target.

Now reboot.target is reported as enabled.

# systemctl disable reboot.target
Removed "/etc/systemd/system/ctrl-alt-del.target".

Now reboot.target is reported as disabled again.  Why doesn't the
ctrl-alt-del.target symlink under /lib/systemd/system count?

Maybe related: why does 90-systemd.preset enable reboot.target but
disable poweroff.target (for example)?
