Some packages ship an older version which does not recognise
aarch64. To overcome this, we just update these scripts when
necessary.

I completely ruined this now and therefore I had to make
it new again:
* I split the parameters into smaller chunks now and added
comments about why we have chosen those.
* I move it all to configure_build() since we do not need
to check if the host architecture is 64 bit capable, but
the architecture we are building for.

We cannot reliably detect in this script any more if the
system has an actual HWRNG (/dev/hwrng always exists).
Therefore we always start the daemon now and let it
deal with what ever comes.

This caused that the xz command was called without any
extra arguments. This will now create the tar archive
first and then pass the archive through xz with our
command line switches.

Changes since V1:
- Tuned some more 'tar'-command lines
- Included 'lfs/core-updates'
- Some fine-tuning
Hi,
Current results with V2 (clean builds):
'next':
'packages' => 255 MB
'ipfire-2.19.2gb-ext4.i586-full-core121.img.gz => 319 MB
'ipfire-2.19.i586-full-core121.iso' => 218 MB
Total => 792 MB
'xz-tuning':
'packages' => 228 MB
'ipfire-2.19.2gb-ext4.i586-full-core121.img.gz' => 318 MB
'ipfire-2.19.i586-full-core121.iso' => 207 MB
Total => 753 MB (-39 MB)
It would be nice if someone could review and test these. ;-)
If necessary, I can upload a complete patch.
Best,
Matthias

Hi,
as mentioned in the "list", we're trying to make the archives as small as possible
using 'xz'-compression.
In order to achieve this, this patch tests the size of the memory available on the
host system.
It sets the xz-memory-limit (--memory=[N]Mib) to 70% of the available working memory,
a maximum of four xz-'worker threads' (-T4) and a compression rate of '-8' (-8).
These options are written to the 'XZ_OPT=' environment.
For details see:
https://linux.die.net/man/1/xz
I have set the number of available xz-'worker threads' (-T) to four (-T4), because during
the final tests the '-T0' parameter led to error messages snd stopped: 'cannot allocate memory'.
It wouldn't even run with 90%.
Furthermore, testing with '-T0' led to countless messages filling up '_build.packages.log'.
E.g.:
...
xz: Adjusted the number of threads from 8 to 2 to not exceed the memory usage
limit of 1557 MiB
...
Tests took place on a 32bit-Ubuntu 16.04.4-system with 8 GB RAM and an Intel I7-2600.
Build time was about 04:30 hrs. Perhaps a 64bit-system would perform better (higher
values), but my goal was to make this run on as many systems as possible, so I choosed
these averages.
If minimum requirements (1024 MB RAM) are not met, building stops.
Current results:
'next', untuned:
ipfire-2.19.2gb-ext4.i586-full-core121.img.gz => 332951687 Bytes
ipfire-2.19.i586-full-core121.iso => 228589568 Bytes
'next', XZ_OPT: -T4 -8, 70% RAM:
ipfire-2.19.2gb-ext4.i586-full-core121.img.gz => 329725723 Bytes
ipfire-2.19.i586-full-core121.iso => 217055232 Bytes
These two resulting archives are 14760300 Bytes smaller than before.
Best,
Matthias
