Hello GRUB folks,

I'm working on reiser4 support in GRUB. It is done by means of using our libreiser4 built in "alone" mode, that is without libc, gcc builtins and without not needed features like creating files or filesystem at all.

As GRUB does not have any memory management, we have been implermented simple memory manager which operates on FSYS_BUF of 32k size. GRUB uses it for filesystem related purposes instead of dynamic allocation. But the problem is that this buffer is used by all filesystems GRUB supports them for their own needs and gets corrupted durring attempt_mount() and probably yet another code pathes.

Possible solutions are:

(1) Make all filesystems GRUB have to be used dynamic allocation.
(2) Allocate stand alone buffer for reiser4 purposes.
(3) ???

If you are intersed I will send you a patch against grub-0.93 and last libreiser4.
