Description of problem:

When specifying an nfs path containing an ipv6 address, either on the kernel cmdline as

ks=nfs:[fc00::xxxx:xxxx]:/path/to/kickstart

or in the kickstart file as the path for stage2:

nfs --server [fc00::xxxx:xxxx] --dir /opt/opsware/boot/kickstart/rhel60x64

the nfs address is parsed wrong.

Version-Release number of selected component (if applicable):

anaconda 13.21.195 , possibly earlier as well

How reproducible:

Always

Steps to Reproduce:
1. Boot RHEL 6.4 install cd with kernel argument "ks=nfs:[ipv6address]:/path/to/ks"
2. Wait for anaconda to load
3. Anaconda complains of not being able to load the kickstart file, and logs show malformed parsing of the url

Actual results:

For an example ipv6 address of [fc00:123:1:0:250:56ff:fe00:1234]

The NFS url gets parsed as:
opts="[fc00"
host="123"
path="1:0:250:56ff:fe00:1234]:/path/to/kickstart"

Expected results:

Same example address:

opts=""
host="[fc00:123:1:0:250:56ff:fe00:1234]"
path="/path/to/kickstart"

Additional info:

The most likely culprit is
void parseNfsHostPathOpts (char *url, char **host, char **path, char **opts)
from loader/nfsinstall.c in the anaconda source tree. The parsing doesn't take into consideration the case in which host is an ipv6 address.
