We must be reading different versions of generate_random_uuid ;-)

/* Structure of super block on disk */
struct reiserfs_super_block
{
/* 0 */ struct reiserfs_super_block_v1 s_v1;
/* 76 */ char sb_mnt_version[16];
/* 92 */ char sb_mkfs_version[16];
/*108 */ char sb_fsck_version[16];
/*124 */ char sb_unused[204-16-16-16-SB_SIZE_V1] ;
/* zero filled by mkreiserfs */ };

Show me the part where it knows what a uuid is. It should at least be able
to show the uuid set by the kernel.

Please don't take this the wrong way, this is a good (and simple) patch
that adds a cool feature. We just need to do a better job of having the
utils support the features before sending the patch it. It does a better
job of proving we've tested the feature and that kernel patch fully meets
our needs.
