Hello everyone,
Suppose I wanted to write an ext4 driver for FreeDOS and integrate it
such that it's possible to use ext4 on a system partition. And let's say
this plan materialized - would this have any effect on existing DOS
software? I'll go on why do I even consider this, but I want to know if
I'm not running the risk of breaking some functionality for let's say
some cool games or their installers.
The reason I'm asking is because I've encountered software that forces
me to forcibly reboot my DOS machine and this causes all mounted FAT
partitions to break down. It happens because the software hanged itself
and doesn't react to any input. FreeDOS' own filesystem repair tools and
GNU dosfstools can't even repair all of the damage. So I understand that
using FAT is harmful as it runs the risk of breaking during an
unexpected power shortage in such ways that it'd make btrfs blush.
To rectify this, I would need to move to a different filesystem. ext4
seems obvious for me because it's well documented, rock solid (by now, I
know it would break in 2009) and it has a journal so we can always
recover from any power loss induced filesystem damage.
Best regards,
Michał
