I'm interested in configuring grub to allow selecting different sets of
kernel parameters at boot time. I know I can edit the boot command line
by hand, but this is tedious and error-prone. (An example might be to
choose between the Nouveau and Nvidia drivers by selecting the
appropriate menu entry). And of course I'd want this updated
automatically with each new kernel version (i.e. each kernel would then
have two alternative entries).
How feasible is this?
On every version of Fedora in the last ten years or so, the basic
network configuration is stored in files under /etc/sysconfig. When the
machine boots or I run "systemctl restart network" (or "service network
restart"), those files determine how the network gets set-up. After
that, I can change the configuration with several tools. For example, I
can run something like,
# ip address add 192.168.0.37/24 dev eth0 label eth0:xx
and a new interface alias will be created. But how do I make this alias
resilient so that it will appear automatically after a boot or a network
For a primary interface with a static address, I may be able to add the
information as IPADDR2 (etc) in ifcfg-eth0. But how do I do this if the
primary interface gets its address via DHCP?
