After ruining my previous installation, I did a factory reset, updated (to 2.575) and reconfigured everything.
Later, I found out I made a typo in the alias for a samba share.
In the settings you can update the field and when you click ‘save’ the new name is shortly visible in the with shares.
After that it returns to the old name and after a reboot it still isn’t updated.
Not really a major issue; just drop the share, create a new one and enter the name more carefully and rescan everything.
But, we don’t need a broken window, do we?
