When trying to mount an NTFS removable disk, the following error is encountered:
Filesystem type ntfs3,ntfs not configured in kernel
This seems to be related to this issue.
However, there is no way to write mount_options.conf using the builtin NixOS modules.
For those Googling here, here is a temporary solution:
environment.etc."udisks2/mount_options.conf".text = ''
[defaults]
ntfs_defaults=uid=$UID,gid=$GID,prealloc
'';
Then for good measure, manually restart udisks2 with sudo systemctl restart udisks2.
However, while this solution does work, it’s not ideal for a few obvious reasons, like the fact that udisks2 does not automatically restart. Should the udisks2 NixOS module be extended to provide configuration options for mount_options.conf? Presumably this issue will eventually be fixed in upstream software (maybe Dolphin/Kio in this case?) but maybe having these options would be useful anyways? Or perhaps I am blind and there is already a better solution?
