You can use a DMG package with FUT/FEU as @mvu detailed. It will work perfectly fine. You can also do this through CLI if you wanted. I would probably do it though CLI myself and run this with a policy so its easier to edit.
Something like this will create the file, and write whatever you want to the file.
#!/bin/sh
## postinstall
#*=============================================================================
#* Define logged in user
#*=============================================================================
DIV1='echo ####################################################################'
DIV2='echo --------------------------------------------------------------------'
DIV3='echo ....................................................................'
ActiveUser=`/bin/ls -l /dev/console \
| /usr/bin/awk '{ print $3 }' \
| tr "[a-z]" "[A-Z]"`
ActiveUserRealName=`dscl . -read /Users/$ActiveUser \
| grep RealName: \
| cut -c11-`
if [[ -z $ActiveUserRealName ]]; then
ActiveUserRealName=`dscl . -read /Users/$ActiveUser \
| awk '/^RealName:/,/^RecordName:/' \
|sed -n 2p | cut -c 2-`
fi
userInfo () {
echo; $DIV1
echo "User Information:"
if [[ "$ActiveUserRealName" == "$ActiveUser" ]]; then
echo "$ActiveUserRealName (Local Admin)"
else
echo "$ActiveUserRealName ($ActiveUser)"
fi
$DIV1
}
userInfo
#*=============================================================================
#* Relocate files
#*=============================================================================
if [ -d "/Users/$ActiveUser" ]
then
echo '/Users/$ActiveUser Valid. Writing Log'
sudo touch /Users/$ActiveUser/.config
echo "this is a line" > /Users/$ActiveUser/.config
exit 0
else
echo '/Users/$ActiveUser Not Valid. Do nothing'
exit 1
fi
exit 0 ## Success
exit 1 ## Failure
Something like this would be able to move a file. For example if you placed the file in a staging location with a policy, you could then move it to the users profile.
#!/bin/sh
## postinstall
#*=============================================================================
#* Define logged in user
#*=============================================================================
DIV1='echo ####################################################################'
DIV2='echo --------------------------------------------------------------------'
DIV3='echo ....................................................................'
ActiveUser=`/bin/ls -l /dev/console \
| /usr/bin/awk '{ print $3 }' \
| tr "[a-z]" "[A-Z]"`
ActiveUserRealName=`dscl . -read /Users/$ActiveUser \
| grep RealName: \
| cut -c11-`
if [[ -z $ActiveUserRealName ]]; then
ActiveUserRealName=`dscl . -read /Users/$ActiveUser \
| awk '/^RealName:/,/^RecordName:/' \
|sed -n 2p | cut -c 2-`
fi
userInfo () {
echo; $DIV1
echo "User Information:"
if [[ "$ActiveUserRealName" == "$ActiveUser" ]]; then
echo "$ActiveUserRealName (Local Admin)"
else
echo "$ActiveUserRealName ($ActiveUser)"
fi
$DIV1
}
userInfo
#*=============================================================================

#*=============================================================================
if [ -d "/Users/$ActiveUser" ]
then
echo '/Users/$ActiveUser Valid. Writing Log'
sudo mv /some/staging/file/path/.config /Users/$ActiveUser/.config
exit 0
else
echo '/Users/$ActiveUser Not Valid. Do nothing'
exit 1
fi
exit 0 ## Success
exit 1 ## Failure
Both the scripts could be cleaned up a bit, but should get you going if you are interested. You may also want to add some chmod bits to set file permissions.
