Create a file in /etc/sysconfig/network-scripts named route-(ifname)

See section 2.4.4 of the RHEL 7 networking guide (RHEL is same as Centos) here for complete details:

Change sudoers remotely on CentOS Linux

I've been asked to give someone sudo rights across an entire environment without the benefit of something like puppet or chef or cfengine et al.

What I've come up with so far is this:

ssh -t miaprbicsra04v sudo -S /bin/echo "rsherman ALL=(ALL) NOPASSWD: /sbin/service /bin/rm /usr/bin/du /bin/df" >> sudo tee /etc/sudoers

Right now that's just to one host, but I plan on substituting a list of hosts once I get farther along. Problem is, the output hangs on the tee command. Not sure why. Any suggestions?

Forcing linux kernel 3 to recognize cdrom as hdX on centos

I have a problem with older version of anaconda linux installer. I have upgraded kernel in my distro, but, when this anaconda boot with new 3.4.52 kernel, can NOT find cdrom. As far as I understand, this is because the new kernel recognize cd drive as srX, scdX instead of older hdX with 2.6.18. At the moment I can not upgrade anaconda and forced this kernel to recognize it as before.

Are there any kernel command line argument, kernel config or something else for kernel 3.4.52 to recognize this cdrom as hdX?
