vidcontrol

[cybersans]

in the freebsd, i can set auto resolution via rc.conf with command
allscreens_flags="MODE_XXX"

where XXX is the number of the resolution i want to set from the list generated via vidcontrol -i mode

so, in opnsense, where should i put the allscreens_flags?
there is no rc.conf in the /etc path

thank you
