Unhappy Unable to mount root fs via NFS minicom2440 and Fedora 17


I am trying to get the nfs-server to work so that I can begin to program my mini2440 ellk kit. If it were not for this last snag I would be on my way.

well you are going to have more problems
Fedora 17 is a dead and unsupported version
and in about a week or 2 fedora 18 will also be unsupported

please install the current version of fedora
Fedora 20
then in 6 months install fedora 21
then fedora 22 ,6 months after that

you can stretch the upgrade cycle to 13-18mo, no need to upgrade every 6mo with Fedora.

I purchased a ELLK kit (mini2440) about a month ago. I would switch to a different version other than Fedora 17 if not for the fact that the organization that supports it is not that familiar with ubuntu. This is all very new to me and I would prefer a common platform in which I can learn from one in which the other parties are intimately acquainted. It would appear that with the onslaught of constant change much of what was meant to facilitate a learning environment including my kit is evaporating.

any one version of fedora only has 13 months of support , not 18 ( suse has 18 month)
and it has never been supported doing a upgrade skipping a version

so say installing fedora 19 then trying to upgrade to 21 ,then trying to upgrade to 23
is not going to work out well

and to add; each new version of fedora can be VERY different from the last one

mysql being replaced by maria db ...
system v being replaced by system D...
the introduction of pulse audio( way back) ...

a new reinstall every 6 months is still recommended way to upgrade fedora
or using "fedup" to move to the next version but NOT skipping a version

then fedora is NOT a good idea for you to use

Fedora BY DEFINITION is a VERY FAST passed "Research and Development " distro
One that CHANGES VERY VERY VERY FAST

so fast in fact that a lot of software will not yet build with the VERY NEW versions of software included in fedora

most programs will need hacking just to build with the very new software


You might want to have a look at a long term support OS like CentOS 6.5

Cent is a FREE rebuild of RedHat

so you moved from a rpm based system using "yum"
RHEL
CentOS
Fedora
suse ( uses zypper and rpm's )
and some others

to the OTHER camp
the Debian based distro
Debian
Ubuntu
Mint
and others that use "apt-get"


so much for not making RADICAL changes

ubuntu is VERY VERY different that fedora,rhel,cent

very different
