[Bug-mcron] mcron, daemon shall recognize itself

[Jean Louis]

Hello,

I have noticed that:

- mcron shall be run by user, which is good, like mcron -d for example

I have such setup that as user I would need to put mcron either in shell
login or in some startup script with X Window System. So I put it in
startup script of Window Manager.

When I exit window manager, and come back, the mcron is again loaded
into memory, the multiple instance.

My opinion is that mcron shall recognize if there is instance running
by that single user, and shall not be loaded in that case.

I ask for that to be improved. Of course each user could make it for
themselves to check if/not, but is user friendly to put such important
program to recognize itself rather.
