It doesn't lose the license here after a force kill using XFS on Jessie (Upgraded last night, promptly spent today fixing the mess it made of GRUB and the VNC server
)
Journaling filesystems:ext3, at least by default is journaling. Disabling the journal will essentially make it an Ext2 filesystem, running under the Ext3 driver.
If you've turned journaling off specifically using tune2fs, then frankly I'd call that 100% unsupported by any distribution, let alone MC.
The only remotely good reason I can even think of off the top of my head for turning off journalling is for ultra-paranoid file encryption purposes.
There is *no* OS compatibility issue that I'm aware of. If you've turned it off because you wish to use Ext2FSD on Windows, don't- This works perfectly well with the journal turned on (Ext3 is backwards mount compatible with Ext2, and for that matter Ext4 is also compatible if you don't play with the tune2fs options)
Whilst turning off journaling may increase the filesystem speed access/ write speeds very marginally on a heavily disk dependant system, if that was your aim, it's frankly a plain stupid idea- Invest in a decent SSD / RAID setup instead.
Again, I can't think of *any* software that will react differently on a journaled filesystem. Please enlighten me
