By changing

So that I can realize when it fails, and see a bit more verbose output, and still know what is executed, I see the following output on the initial tty1:

> artixlinux login:  setfont:  INFO setfont.c:161 do_loadfont:  Loading 512-char 11x22 font from file /usr/share/kbd/consolefonts/ter-v22n.psf.gz

Then, by looking at what command lines were executed:

> % cat /run/setfont.log

It seems it fails on "setfont ter-v22n -C /dev/tty1", but I actually executed all of them by hand without error, so I couldn't reproduce it by hand:

> % sudo su

> [m1 vasqueja]# setfont ter-v22n -C /dev/tty1
> [m1 vasqueja]# setfont ter-v22n -C /dev/tty2
> [m1 vasqueja]# setfont ter-v22n -C /dev/tty3
> [m1 vasqueja]# setfont ter-v22n -C /dev/tty4
> [m1 vasqueja]# setfont ter-v22n -C /dev/tty5
> [m1 vasqueja]# setfont ter-v22n -C /dev/tty6
> [m1 vasqueja]#

So no failure by hand, just randomly when executing the one-shot...

Thanks !
