20.6 System Startup on Debian, Raspberry Pi OS, and Ubuntu
Debian and Ubuntu also use systemd for the system startup (see Table 1.3). Figure 20.1 therefore also applies to these distributions. However, Init-V compatibility plays a somewhat larger role on Debian or on Ubuntu to this very day.

root# systemctl grep LSBUNIT ACTIVE SUB DESCRIPTIONhddtemp.service loaded active exited LSB: disk temperature ...postgrey.service loaded active running LSB: Start/stop the postgrey ...spamass-milter... loaded active running LSB: milter for spamassassin|
