This is for SPS2001.

I'm trying to set the "Publish this document after check-in"-checkbox to
default checked (pubform.asp in each workspace), and changes the

<INPUT TYPE="checkbox" NAME="PKM_SharingButtonGroup" ID="PKM_SharingPublic"
CLASS=checkbox>

to

<INPUT TYPE="checkbox" NAME="PKM_SharingButtonGroup" ID="PKM_SharingPublic"
CLASS=checkbox checked="checked">
(or <INPUT TYPE="checkbox" NAME="PKM_SharingButtonGroup"
ID="PKM_SharingPublic" CLASS=checkbox checked> which is more standard)

But after a restart this resets to the original code, and the checkbox is
again not checked.

How do I make this stick? Or are there other ways of doing this?
