LZ4 creates bigger archives than XZ, but decompression time is only half
as long on a ASRock E350M1 with an SSD, shaving off half a second from
the overall boot time of four seconds.
The patch is taken from Ubuntu [1] and has the change-log entries below.

Using 10% of RAM for /run is a good default, but not suitable for all
systems. 10% might be too small for system with less memory (e.g.
virtual machine with 160 MiB RAM) or too big (VM host with 256/512 GiB
RAM). A too small /run partition leads to not enough space on it. If the
/run partition is huge, systemd's journald will consume lot of memory,
because it defaults to using at most 15% of the respective file system
of /run/log/journal.
Adjusting the size of /run via an entry in /etc/fstab is not sufficient
since journald calculates it limits before systemd remounts /run with
the small size. Therefore journald could occupy the full /run partition
with its logs.
Allow specifying the size of /run by adding a RUNSIZE configuration
variable and a initramfs.ramsize= boot argument. Mounting /run must be
done after reading the configuration.

Some systems are working alright with the old default of BUSYBOX=y and
no busybox installed. We should only force use of busybox if another
package installing initramfs scripts needs it.
Change the default from BUSYBOX=y to BUSYBOX=auto, and give that the
old semantics.

Currently we silently fall back to klibc if BUSYBOX=y but we can't
find it. This can result in an unusable initramfs, so fail instead
of continuing.
This mitigates bug #783297.

/usr/share/initramfs-tools/modules looks like it could be a live
configuration file, but it is not. Add a short comment to the file,
then strip it when copying to /etc/initramfs-tools.

Specifying root=/dev/nfs doesn't really do anything without also either
specifying boot=nfs or changing BOOT= in initramfs.conf:
/dev/nfs)
[ -z "${BOOT}" ] && BOOT=nfs
;;
At which point, you could just as well not specify root=/dev/nfs at all.
This breaks the historical method for network booting with nfsroot with the
kernel arguments:
ip=dhcp root=/dev/nfs
I guess the check to make sure BOOT wasn't already set was changed in order to
fix putting boot= anywhere in the boot commandline:
http://bugs.debian.org/453294
But it seems to me the correct thing to do in that case would be to specify
boot=live after root=/dev/nfs... since the order of the argument processing
matters, rather than preferring the result of one argument over another.
Why is BOOT=local defined in initramfs.conf at all?
What about only setting BOOT=local if $BOOT is undefined, after all the
argument processing is done.

"It seems to me that the "Loading essential drivers" step is
unconditionnaly loading all modules listed in

initramfs-tools currently requires a device to be hard-coded, but this
is not much use if the network device is not known ahead of time. If
the device specified in either /etc/initramfs-tools/initramfs.conf or
on the ip=xxx kernel command line.
usefull for multiple net devices.

Albin Tonnerre sent a patch fixing the initramfs LZO decompression,
so heres my fix for initramfs-tools to have compete compression
support. Tell me if you want me to open a new bugreport.
On a side note: this will only work with a patched kernel (might be
upstream with 2.6.34), its a good idea to include a warning for those
running 2.6.33 from experimental
[ adding it on TODO of Lenny linux-2.6 2.6.32 ]

this version uses /etc/initramfs-tools/initramfs.conf to determine
the compression method, checks kernel and userspace support with
fallback to gzip. Since LZO didnt work for me at all with 2.6.33
I left that out for now.

we don't need to any more. TODO: lilo might still want .bak's.
[ merge 0.92bubuntu9 + fix manpage
note: indeed the precaution seems no longer needed these days,
but is potentially harmful when /boot space is small. ]

this allows for a much smaller initramfs and thus faster boot.

Now that d-i won't create /etc/initramfs-tools/conf.d/driver-policy
in all cases, I think reference to is mostly useless.
|
|
Please mention in initramfs.conf that the values specified there can
be overriden via /etc/mkinitramfs/conf.d. This is important since d-i
will now use /etc/initramfs-tools/conf.d/driver-policy to set MODULES.

Based on a patch from maximilian attems, thanks!
* Handle module arguments in /etc/mkinitramfs/modules
* Do hookscripts at generation time. Drop things into
/usr/share/initramfs-tools/hooks or /etc/mkinitramfs/hooks
* Make sure local-bottom and nfs-bottom get created
Thanks to Karl Hegbloom for these three patches!
* Prune stray echo from call_scripts
* Load raid1 for now so that md setups will work.
* Detect ide modules load
Thanks to Jeff Waugh for initial testing of this!
