The "DAEMON_OPTIONS" option in /etc/default/mdadm doesnt't work

[114514foxes]

Up-to-date Debian 12 x64.
Here is my /etc/default/mdadm:

Code: Select all

AUTOCHECK=true
AUTOSCAN=true
START_DAEMON=true
DAEMON_OPTIONS="--syslog --test --pid-file /root/z_mdadm.pid"
VERBOSE=true

I've run dpkg-reconfigure mdadm a couple of times, but the DAEMON_OPTIONS does not work.
The file "/root/z_mdadm.pid: does not exist at all.
MDADM does not send an e-mail at the startup either.
The options written by me does not present in the process list either.

Code: Select all

# ps aux | grep mdadm
root         425  0.0  0.0   3580  1796 ?        Ss   10:26   0:00 /sbin/mdadm --monitor --scan

Hello,

I also have run "update-initramfs -u", nothing is changed.

Hello,

According to this bug report, /etc/default/mdadm is only used by the SysV init script (not by systemd):

• Debian Bug report logs - #850180 mdadm: systemd units do not obey /etc/default/mdadm, esp DAEMON_OPTIONS=--syslog

     * Uploading to experimental.
