Note: The question marks from Dummy1 to GetSpecialFileSize on the "available since system version" field are mainly there because I think that most of these are necessary for the main system to function, so theoretically that would mean that since the creation of the 3DS these were available, or since launch if that makes more sense. But because of the peculiar nature of some of the functions, they will remain question marks until they can be confirmed 100%.
When access rights are required for a command, at least one of the bits in the process access info specified in the above table for the command must be set. Error 0xD9004676 is returned when a process attempts to use a command which it doesn't have access rights for the command. The exheader access info field is all zero's for most applications. Note that the permissions listed in the above table is for system-version v2.x, therefore permission bit(s) added with newer FIRM may be missing from this.
Each session for fs:USER has separate permissions, initially these are set to all zero's for new fs:USER sessions. The permissions/etc for fs:USER sessions are initialized via FS:Initialize(loaded from the user process exheader).

Filesystem service "fs:LDR"
This service is identical to fs:USER, except FS:OpenArchive archive 0x2345678E can only be accessed with fs:LDR.
ProgramRegistry service "fs:REG"
| Command Header | Description |
|---|---|
| 0x000100C6 | Dummy1 |
| 0x040103C0 | Register |
| 0x04020040 | Unregister |
| 0x040300C0 | GetProgramInfo |
| 0x04040100 | LoadProgram |
| 0x04050080 | UnloadProgram |
| 0x04060080 | CheckHostLoadId |
Only one session can be opened for this service at a time, hence no other processes can use this due to pm-module using this.
SEEDDB
With 9.6.0-X new System_SaveData with saveID 0001000F was added, this seems to be handled by FS-module itself, probably via the new service-cmds added to fsuser. Home Menu and NIM module have access to those commands.
The SEEDDB savedata contains the title-unique seed-data used for the new NCCH keyY generation added with FIRM 9.6.0-X.
