No manual entry for mdcheck_start.timer #man /usr/lib/systemd/system/mdcheck_start.timer
(cat of the file)
/usr/lib/systemd/system/mdcheck_start.timer has no symlink in /etc/systemd/system/. I want to change the start time from Sunday @0100 to Monday @0500. Do I copy that file and change the copy as desired, or symlink it and change the copy, or use some systemctl or other command?
There was no “it”. What there is is all of the above, except there is no such in the list to select.
But it is of course your choice to make your question more attractive by providing information or not.
