I was about to say the opposite until I noticed that one of my main dev machine has its kernel git dir on it because it's an old FS from a previous instance of this machine before an upgrade and it turns out that this FS still had lots of available space to store git trees :-/ So maybe you're right and there are still a bit more than expected out there. However I really think that most users who still have one are in the same situation as I am, they're not aware of it. So aside big fat warnings at mount time (possibly with an extra delay), there's nothing that will make that situation change. At the very least disabling it by default in Kconfig and in distros should be effective. I really don't think that there are still users who regularly update their system and who have it on their rootfs, but still having data on it, yes, possibly. The earlier they're warned, the better. At least now I know I need to migrate this FS. Regards, Willy
