As many know the disk partitioning software that is used in redhat Linux during the install is not as flexable as one would like it to be.

We like to keep several old kernels under /boot and it eats up more space than the default size permits.  

Every time I try to make /boot larger in the disk partitioning gui it keeps on telling me I can not modify this because it is part of ....

I know I can boot the system into rescue mode or I can do a kickstart install to set /boot where ever I want however that is not practical, I would like to understand how I can modify this.

Erasing the redoing the partitioning can be dangerous as I could get a nonstandard install

if you do a custom partition configuration you can create /boot the size you want
if you need to keep several kernel versions, recommend 2gb

I see where you are coming from however it seems pretty sad I need to do all that just to increase one lousy partition that just happens to be /boot

is this for a new system or an existing system you want to modify partitions with?

Technically you dont need any /boot partition on a modern hardware.
If you start with default partitioning you must delete LVM PV, then you can resize partition.
Why would you need it bigger than default half-gigabyte? Each kernel is like 50MB and it keeps 5 around???

you were right, it is not that hard to delete and recreate.  I have an issue with the gui not being able to reize this easy
