Setup Wizard: in Linux, not recognizing the correct mounted Songs folder in Windows

Bug description

In the First-run Setup import section, I selected my osu!stable installation in Windows mounted into linux (/run/media/eurydice/68826360826331AC/Users/coreign/AppData/Local/osu!/) which has the configuration that specifies the Songs folder to be in C:\OsuSongs (which would resolve to /run/media/eurydice/68826360826331AC/OsuSongs/ if I were in Windows).

What I saw was a mere 19 beatmaps (instead of the expected 4000~ish I have on stable), possibly those that are in /run/media/eurydice/68826360826331AC/Users/coreign/AppData/Local/osu!/Songs/ instead of the expected /run/media/eurydice/68826360826331AC/OsuSongs.

I have also pursued some way to import my songs using the Import Files button but apparently it has an undocumented intended use case according to @bdach and my case is not that.

Even if osu!lazer went ahead and read the stable configuration file and parsed the path C:\OsuSongs it pretty much has no way of telling where C:\ is mounted in my linux installation. Therefore I would suggest exposing a more primitive way of importing Songs and Skins directly from folders.

Description	Platform	Path
osu!lazer	Linux	$HOME/Games/osu-lazer/osu.AppImage
osu!stable	Windows	C:\Users\coreign\AppData\Local\osu!\osu!.exe
Songs folder	Windows	C:\OsuSongs
Windows partition mount path	Linux	/run/media/eurydice/68826360826331AC/
osu!stable (mounted)	Linux	/run/media/eurydice/68826360826331AC/Users/coreign/AppData/Local/osu!/
Songs folder (mounted)	Linux	/run/media/eurydice/68826360826331AC/OsuSongs/

Even if osu!lazer went ahead and read the stable configuration file and parsed the path C:\OsuSongs

It does try and do that but will fail in overly custom scenarios like the one described here.

osu/osu.Game/IO/StableStorage.cs

Lines 37 to 68 in f8830c6

	private string locateSongsDirectory()
	{
	var configurationFiles = GetFiles(".", $"osu!.{Environment.UserName}.cfg");
	// GetFiles returns case insensitive results, so multiple files could exist.
	// Prefer a case-correct match, but fallback to any available.
	string usableConfigFile =
	configurationFiles.FirstOrDefault(f => f.Contains(Environment.UserName, StringComparison.Ordinal))
	?? configurationFiles.FirstOrDefault();
	if (usableConfigFile != null)
	{
	using (var stream = GetStream(usableConfigFile))
	using (var textReader = new StreamReader(stream))
	{
	string line;
	while ((line = textReader.ReadLine()) != null)
	{
	if (!line.StartsWith("BeatmapDirectory", StringComparison.OrdinalIgnoreCase)) continue;
	string customDirectory = line.Split('=').LastOrDefault()?.Trim();
	if (customDirectory != null && Path.IsPathFullyQualified(customDirectory))
	return customDirectory;
	break;
	}
	}
	}
	return GetFullPath(STABLE_DEFAULT_SONGS_PATH);
	}

Things may still work if you use the import wizard twice, pointing it at the osu! directory first, and then at the external songs folder location second.

It does not let me select my custom songs folder after selecting the osu!stable installation. It just opens the directory for viewing.

Additionally, if I were to propose other alternate methods for finding a configuration file, after the current behavior of detecting usableConfigFile if the usableConfigFile is still null we could do:

1 - enumerate all osu!{username}.cfg files in the folder, in the case Environment.UserName doesn't match the configuration file name (could happen on Windows with different users)
2 - abuse the default osu!stable installation path being %localappdata% and try to parse the username from the canonicalized path string of ., because AppData's parent is a directory with the username.

C:\Users\coreign\AppData\Local\osu!\ // absolute form of "." contains an "AppData" directory.
//       ^^^^^^^ ^^^^^^^
//       ^parent ^child

3 - avoid all such shenanigans and allow providing a songs folder directly from the UI. I believe this is the least intrusive option.

and once again, even if we have the correct config file and parsed the songs directory path, lazer has no way of telling where it is supposed to be if it's not a relative path, since that would make an absolute path like C:\OsuSongs which is not a valid linux path in the first place, and even if it were, the mount point is unknown.

i still haven't figured out a way to import any maps over to lazer from my windows installation other than manually exporting every map one by one and importing them in lazer. any ideas?

lazer data folder is not OS-dependent (at least between windows and linux), so you can always do the import on windows. Or maybe temporarily move back the song folder to where it should be.

how could I not think of moving the songs folder back where it's supposed to be lol. thanks. why i had my songs folder elsewhere was primarily because of the windows long path constraints and whatnot breaking loading some maps on stable.
