This module provides syslog functionality in the initrd.
This is especially interesting when complex configuration being
used to provide access to the device the rootfs resides on.
When this module is installed into the ramfs it is triggered by
the udev event from the nic being setup (online).
Then if syslog is configured it is started and will forward all
kernel messages to the given syslog server.
The syslog implementation is detected automatically by finding the
apropriate binary with the following order:
rsyslogd
syslogd
syslog-ng
Then if detected the syslog.conf is generated and syslog is started.
Bootparameters:
syslogserver=ip Where to syslog to
sysloglevel=level What level has to be logged
syslogtype=rsyslog|syslog|syslogng
Don't auto detect syslog but set it

It ends up installing the label.so control plugin which isn't supposed
to get installed into the initrd. this makes cairo and libX11 and all sorts of
things move into the initrd that aren't supposed to.
I am not happy about this. It shouldn't be the job of dracut to do this. The initscripts should
deal with the plain /dev/.initramfs/ifcfg/ directory accordingly. Doing this for now because
notting insists upon it. We need to clean this up after we network option passing working.
If you're using a persistent overlay, you might want to reset it
at boot time if it has become corrupted somehow. Support using
reset_overlay as a command line optino to do so
The persistent overlay can be specified with an overlay= argument
on the command line. We'll probably try to move this into the
root= syntax soon, but this is the old way that works
livecd-creator previously added 'liveimg' and used root=CDLABEL=;
it's easy enough to support that old syntax for now at least
and it will make it easier to get people testing
Fedora/Red Hat live images are implemented as an ext3fs inside of
a squashfs. Writability is achieved with a device-mapper snapshot
on top of that.
This gives the basic support without a lot of things like persistent
overlays, iso md5sum checking, etc and also with a new basic syntax
that has to be specified as root=live:LABEL=...
As discussed before, it would be nice to be able to specify
the iscsi chap credentials inside the netroot=iscsi:.....
syntax, this patch implements this in a backwards compatible way, like
this:
iscsi:username:pass@127.0.0.1::3260::iqn.2009-01.com.example:testdisk
iscsi:username:pass:reverse:pass@127.0.0.1::3260::iqn.2009-01.com.example:test
The only downside is that the backwards compatibility is broken when there
is an @ in the iscsi target name (very unlikely), that can still be used,
but only like this:
iscsi:@192.168.1.100::3260::iqn.2009-01.com.example:testdi@sk
