I'm trying to mount the NFS root filesystem with TCP instead of the UDP network
man mount and man 5 nfs tell me that I have to add "tcp" or "proto=tcp" to the
mount options. I put them to /etc/fstab and created an initrd accordingly.
10.0.0.1:/nfsroot/10.0.0.2 / nfs tcp,nolock 1 1
The resulting mkrootdev line in the initrd looks like this:
mkrootdev -t nfs -o tcp,nolock 10.0.0.1:/nfsroot/10.0.0.2
After booting Fedora 8, with the custom image, /etc/mtab tells me that the root filesystem is mounted
with the tcp protocol. But, /proc/mounts tells me that it is running with udp.
running "tcpdump udp port nfs" on the nfs server shows me that the nfsroot is
running with udp instead of tcp.
"rpcinfo -p 10.0.0.1" shows me that the nfsd is accepting tcp connections.
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100003 4 udp 2049 nfs
100003 2 tcp 2049 nfs
100003 3 tcp 2049 nfs
100003 4 tcp 2049 nfs

I wasn't able to find a better component. Please change as needed.

Here is a related issue, where nash ignores mount options:
This looks like a duplicate of 240745 as well
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
