Hello, all. For some FS sometimes additional functions are needed. It could be some type of control (e.g. in ZFS manage zpools) or preparation for OS booting (e.g. in FAT put IO.SYS and MSDOS.SYS at the begining of the root directory). While theese functions are quite specific to FS sometimes are important to implement. So I suggest to add to grub_fs a pointer to an array in which fs module can put custom functions. Also in many filesystems it's quite difficult to add a new file or remove already existing one it's often quite easy to exchange 2 files or directories. So I intend to implement a call "swapfso" (FSO=File System Object) at least for fat and ext2. Such a call could be useful to have multiple OS on the same partition or to have multiple configurations of the same OS (e.g. normal and backup). Then I think to have this function in this extended list (even if this function can be implemented for more FS) unless maintainers suggest that such function should be a part of grub_fs. In this case a good idea would be to have 2 modules for fat,ext2,...: one with swapfso and one without for core image. Vladimir 'phcoder' Serbinenko
