copytree() recursively copies the contents of SRC into DEST.
If DEST doesn't exist it is created; if it exists the contents of SRC
get merged into it (duplicate files are overwritten).
If you're using a static network config, you'll want to keep your
nameservers around when NM starts. Write DNS1 (and DNS2, DNS3, etc..)
into the ifcfg file.
Thanks to Mark Hamzy <hamzy@us.ibm.com>
and Will Woods <wwoods@redhat.com> for the patch.
As described in https://bugzilla.redhat.com/show_bug.cgi?id=541410#c2,
if you want NetworkManager to take over an interface that you're using
for NFS root (or other network root device), you need to:
a) set UUID=<uuid> in ifcfg-<iface>, and
b) save the lease file as /var/lib/dhclient-<uuid>-<iface>.lease
This patch should make write-ifcfg handle both these things.
Given that we boot into a modern Linux distribution with the "/run" toplevel
directory, we can easily mount move the whole /run directory to the real
root in the end and have the complete initramfs later on in
/run/initramfs. All log files and /run states are still accessible and
to save space /run/initramfs can be removed later on.
Because the kernel does not mount a tmpfs on /run prior to unpacking the
initramfs cpio image, we have to copy ourselves very early to a tmpfs
and mount it on /run.
Due to lazy umount the old initramfs binaries should
be removed in the end by switch_root.
This feature can be turned on with "--prefix".
We want all "/var/run" information to live in /dev/.run, until the real
root is mounted.
Therefore we mount a tmpfs on /dev/.run, which can/will be bind/move mounted
on /var/run later on.
Format:
bond=<bondname>[:<bondslaves>:[:<options>]]
bondslaves is a comma-separated list of physical (ethernet) interfaces.
options is a comma-separated list on bonding options (modinfo bonding for
details) in format compatible with initscripts.
If options include multi-valued arp_ip_target option, then its values
should be separated by semicolon.
bond without parameters assumes bond=bond0:eth0,eth1:balance-rr
