We've been finding cases where multiple instances of dracut can be launched
simultaneously, resulting in a corrupted initramfs file. This patch makes
dracut write the initramfs to a new file, then move it into place atomically.
/usr/lib/dracut/dracut.conf.d/*.conf can be overwritten by the same
filenames in /etc/dracut.conf.d.
Packages should use /usr/lib/dracut/dracut.conf.d rather than
/etc/dracut.conf.d. /etc/dracut.conf.d belongs to the system
administrator.
The following change makes the check for the nbd port or named export
more robust.
I wasn't sure whether to include sed in the dracut_install() of
module-setup.sh since net already does that (and nbd depends on that).
To use vlan for net boot, you need to specify vlan and ip kernel options
for the boot interface. For example,
vlan=eth1.1:eth1 bootdev=eth1.1
ip=1.2.3.4:1.2.3.4::255.255.255.0:my-hostname:eth1:none
To use bridge for net boot, you need to specify bridge and ip kernel
option for the boot interface. For example
bridge=br1:eth1 bootdev=br1
ip=1.2.3.4:1.2.3.4::255.255.255.0:my-hostname:eth1:none
In my environment, I needs to boot machines from network within
a vlan or on a bridged network. I found curent dracut release
if-up.sh script in 40network module bypass ip setting for both
bridge and vlan interface.
When dracut-lib.sh is sourced it checks the command line (when not using systemd)
as part of the check_quiet() call.
Therefore mount /proc earlier in init.
Avoids the error:
init: 77: /lib/dracut-lib.sh: /proc/cmdline: No such file or directory
The find_kernel_modules_by_path function shouldn't filter out modules not
located underneath the /lib/modules/ver/kernel directory as out-of-tree
drivers may reside in /lib/modules/ver/extra and updated drivers in
/lib/modules/ver/updates.
