The reason I wrote that way is because my boot.msg contains the following:

Checking file systems...
fsck 1.36 (05-Feb-2005)
Reiserfs super block in block 16 on 0x349 of format 3.6 with standard
Blocks (total/free): 2008112/1231671 by 4096 bytes
Filesystem is clean
Replaying journal..

Am I correct in viewing the whole thing, super block plus tree
structure, as the "file system?" It would seem that first there is a
check for a valid super block, then the tree is checked for consistency,
and only then is the journal replayed. (Other journalling f ilesystems
may vary in specifics, of course.)
