Can't launch distros in SD cards

[DDoSolitary]

One of my users of the LxRunOffline project reported that he got 0x80070057 error when launching distros that are installed to an SD card and I guess it also applies to distros installed by WslRegisterDistribution.

SD cards do not support stable GUIDs, which we require for the root filesystem. Installing to an SD card is not currently a supported scenario.

Why does LxCore Driver need a "stable" GUID of that installation volume? mountvol command can show the GUID of that SD card. Will there be any difference between external SD card reader and in-built SD card slot?

#449 (message). Nipping to keep discussion in one place.

@therealkenc In my opinion, this issue isn't related with #449. Moving WSL installation is already supported but in a special way. Hold tight, programming idea ahead!

Look carefully how wslconfig /upgrade command works (cough). It completely MOVES the Linux folders from rootfs to wslfs directory. So what does it do? The strings, rootfs and wslfs, are stored as struct _UNICODE_STRING which are passed to struct _OBJECT_ATTRIBUTES.ObjectName member. Then these ObjectAttributes variables are passed to NtCreateFile() or NtOpenFile().

Both of the cases the OBJECT_ATTRIBUTES.RootHandle (comes from CreateFile()) are same. So my assumption is that, if someone change the base path or RootHandle (where WSL installed) then WSL installation can easily be moved.

Hence #449 is a user mode issue and this is a kernel mode issue (where LxCore wants stable GUID).
