Not quite right; here's the content of /boot on the testbed
machine :
[root@localhost btth]# mount -t ext3 /dev/sda1 /TEST
[root@localhost btth]# cd /TEST
[root@localhost TEST]# ls

Within that, it's CentOS that grub knows about -- but it does
also know there's more :
[root@localhost TEST]# cd grub
[root@localhost grub]# ls
device.map grub.conf.save minix_stage1_5 ufs2_stage1_5
e2fs_stage1_5 grub.conf.save.1 reiserfs_stage1_5 vstafs_stage1_5
fat_stage1_5 iso9660_stage1_5 splash.xpm.gz xfs_stage1_5
ffs_stage1_5 jfs_stage1_5 stage1
grub.conf menu.lst stage2
[root@localhost grub]# file menu.lst
menu.lst: symbolic link to `./grub.conf'
[root@localhost grub]# cat grub.conf
