Ubuntu 9.04 PS3 kboot doesn't have Ext4 filesystem support

[xbmc50]

As summary says, kboot doesn't support Ext4 filesystem and installing Ubuntu for that will result in non-booting system.
Actually more of an request but bug report, but unfortunately I don't know how to make them?

true that this is not really a bug more of a limitation of the version of kboot used. but there must be some way to get this to work. i found this site wich seems to say that this ver of kboot supports ext4 but i don't know enough to try it. with the weekend i will have plenty of time to play around so anything that can be tried let me know

I don't think Ext4 is "supported" by kboot. Maybe it works, but you would have to test to make sure of it (kboot's kernel is OLD).

To support ext4 properly, we will probably have to switch to petitboot (as soon as it gets packaged here or in Debian).

There is way to bypass this problem easily by creating /boot partition during install with ext3 support and setting it bootable. Discussion link to psubuntu topic

There are reports that geoff's latest testing build already support ext4

Ubuntu 9.10 has the same problem. It installs to an Ext4 filesystem, but kboot doesn't support Ext4.

By now kboot is depricated, and petitboot should be used:

It has perfect support for Ext4.

If this issue still creates non booting installs with newer releases of Ubuntu it should probably be re-filled against the installer for the new version. Being as this is not technically a bug, marking as invalid.
