Re: [coLinux-users] reiserfs error during boot, but I have xfs?

[Ian B. <ib...@gm...>]

Ok, I think what Brian was talking about is why are there errors at
all here. I have a feeling that the way the new 2.6.8 kernel works is
that it doesn't have any filesystem drivers compiled into it, but
instead loads them at boot time. The only way to do that is by loading
an initrd and testing your filesystem for all the different filesystem
types. Hence, the error messages. (I.E. its trying to fsck-like-test
each filesystem driver against your partition, and the only one that
works, is the one that loads). Its a rather brute-force attack, but
its quite good if you want to ship out a generic kernel to a whole
slew of systems and insure that it works on all of them.
