How do you specify inode count in with a kickstart file?

I have a situation where I need to increase the inode count of a filesystem at it's kickstart. The following is not working:

Code:

clearpart --drives=sda --initlabel --all
part /boot --fstype=ext4 --size 512 --ondrive=sda
part pv.02 --size=1 --grow --ondrive=sda --bytes-per-inode=4096
volgroup os_root pv.02
logvol / --fstype=ext4 --vgname=os_root --size=5120 --name=root_vol
logvol /home --fstype=ext4 --vgname=os_root --size=5120 --name=home_vol
logvol /var --fstype=ext4 --vgname=os_root --size=1024 --name=var_vol
logvol /opt --fstype=ext4 --vgname=os_root --size=5120 --name=opt_vol
logvol /tmp --fstype=ext4 --vgname=os_root --size=1024 --name=tmp 
logvol swap --fstype=swap --vgname=os_root --size=4096 --name=swapvol

--bytes-per-inode apparently is depricated and the new thing is --fsprofile but I have no idea how to specify the inode count using it.

Anyone know how to do this?

Per RH:

--fsprofile= - Specifies a usage type to be passed to the program that makes a filesystem on this partition. A usage type defines a variety of tuning parameters to be used when making a filesystem. For this option to work, the filesystem must support the concept of usage types and there must be a configuration file that lists valid types. For ext2, ext3, ext4, this configuration file is /etc/mke2fs.conf.

In case you don't have a copy of the file here is one:

~]# cat /etc/mke2fs.conf
[defaults]
base_features = sparse_super,large_file,filetype,resize_inode,dir_index,ext_attr
default_mntopts = acl,user_xattr
enable_periodic_fsck = 0
blocksize = 4096
inode_size = 256
inode_ratio = 16384

[fs_types]
ext3 = {
features = has_journal
}
ext4 = {
features = has_journal,extent,huge_file,flex_bg,uninit_bg,dir_nlink,extra_isize
auto_64-bit_support = 1
inode_size = 256
}
ext4dev = {
features = has_journal,extent,huge_file,flex_bg,uninit_bg,dir_nlink,extra_isize
inode_size = 256
options = test_fs=1
}
small = {
blocksize = 1024
inode_size = 128
inode_ratio = 4096
}
floppy = {
blocksize = 1024
inode_size = 128
inode_ratio = 8192
}
big = {
inode_ratio = 32768
}
huge = {
inode_ratio = 65536
}
news = {
inode_ratio = 4096
}
largefile = {
inode_ratio = 1048576
blocksize = -1
}
largefile4 = {
inode_ratio = 4194304
blocksize = -1
}
hurd = {
blocksize = 4096
inode_size = 128
}

I've paid attention that you use bytes-per-inode, that is file system related parameter, in line that define physical volume of LVM, that definitely does not suit. Use it in FS related line.
