Summary: Advisory: Debian's current initramdisk scripts break
with an ext4 root
Product: File System
Version: 2.5
KernelVersion: 2.6.28
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: enhancement
Priority: P1
Component: ext4
AssignedTo: [email protected]
ReportedBy: [email protected]
This is just a heads-up to hopefully save other people some time. I'm running
2.6.28 with debian/unstable, finally converted the root to ext4, and discovered
that Debian with an initrd can't boot it because the initrd scripts apparently
decide it is an ext3 filesystem with unsupported features. Not that they report
this: instead you get an ENODEV message that had me convinced ext4 wasn't
registering itself or some other such weirdness. Works fine if you use a
"rootfstype=ext4" kernel boot parameter, or no initrd.

I traced the problem thru the Debian initrd scripts to klibc/bin/fstype and
have filed a Debian bug on it. If kernel-hackers are the ultimate upstream
klibc source, please let me know and I'll refile it in other/klibc/kinit.
# /usr/lib/klibc/bin/fstype /dev/sda5 //a 100% made-from-scratch ext4 fs
