So what needs to be done is place an image back once in a while. It
should be possible to create a GRUB command for that, I guess. :-)
Why a command? A better way, IMO, is using some variables stored in file.
It could be presented as array SAVED_INTEGER of integers and SAVED_FLAGS
of flags.
Then with command
initsaved <file>
where <file> must be created from OS (what about a tool or shell script?)
then
initsaved /grub2/savedvars
if [[ SAVED_INTEGER[0] -ge 10]]; then
defwin = "";
defrest="--default";
else
defwin = "--default";
defrest="";
fi
menu $defwin windows
{
... # Load windows
((SAVED_INTEGER[0]++));
}
menu $defrest restore windows
{
... # Restore windows
SAVED_INTEGER[0]=0;
}
menu reset counter
{
SAVED_INTEGER[0]=0;
}
timeout=10;
In this way first 10 times $defwin expands to --default and "Load
windows" becomes default. Afterwards $defrest expands to --default and
"restore windows" becomes default
