Hi
<Backstory> As some of you may remember, I was one of the organisers of
the LinuxLive event last year and was responsible for remastering two of
the distros we gave away at the the event.
I used UCK (Ubuntu Customisation Kit) to remaster both Ubuntu and
Linuxmint. I wrote a script as a wrapper around the uck-remaster
command. </Backstory>
Recently I wanted to create a custom version of UbuntuGnome, so I made a
copy of the build script and UCK remaster profile and altered them to
suit the current build requirements (i.e. iso used, iso name, packages
to install/remove, etc).
When I was remastering Ubuntu/Mint for the event, a build would take
45mins to 1 hour (approx.)
This lead to my current predicament....
When I try and do a build now, it is still not finished after 12 hours.
I left the script going for approx 12 hours and mksquashfs was only 67%
complete when I decided to kill the script. I calculated that the script
would need approx. 18 hours to do a full run.
For the event I was remastering Ubuntu 13.10 32-bit on Ubuntu 13.10
32-bit. Now I am remastering UbuntuGnome 15.04 64-bit on Ubuntu 14.04
64-bit.
I have the same RAM, CPU and hard drive as when I was remastering for
the event.
Also I have checked the the compression used by mksquashfs. Both then
and now, mksquashfs is using XZ compression.
In order to benchmark the speed of mksquashfs using different
compression methods, I download the test script from:
https://jonathancarter.org/2015/04/06/squashfs-performance-testing/
My results are attached.
I've linked 1 file to this email:
* results.pdf (34.4 kB) hosted on hubiC by OVH: http://ovh.to/AHaRRhM
I believe the uncompressed filesystem size is about 3.5-4.5 GB and
should compress down to about 1.2-1.4 GB based on the results from the
test script.
I used filesystem.squashfs from LL2014_Ubuntu-13.10-32.iso with test script.
Anyone help???

I used Snapfish a few years ago. The prints were reasonable

1) With UKFSN, no as their package didn't include router. Then I used
a wired rooter under the stairs with a separate Wi-Fi Access point.
Since switching have used ISP provided Wi-Fi Router under the stairs
but have retained separate Access Point
2) N/A
3) No
4) N/A, but yes
4a) No under no circumstances
4b) Wi-Fi router under stairs cupboard, Wi-Fi Access Point in Lounge.
Standard antenna(s), standard setup

My house is recent but yes I 9sometimes) use 2 AP

Yes; I have three main homeplug areas and one occasional Also a wired

You did not ask but main wirelessAP is high near roof and reaches

Hi,
1) No, since we have ADSL, so can use whatever hardware we like. I have
a TP-Link W8980.
2) I am considering switching to alternative firmware, but have so far
been impressed by TP-Link's speed of updating and fixing security holes
(the recent NetUSB flaw was fixed in days).
3) I use iperf to test network transfer speeds from the command line.
4) I use powerline adapters (also TP-Link), but only ethernet, since I
rent and hence can't lay cables. They have been extremely reliable.
5) The main thing that improved coverage in my house was using the 5GHz
band. This is because we have a very saturated 2.4GHz band on my street.
Hope this helps!
James

Others have given responses to the other questions, but the best Wifi
access points I've ever used (by some margin) are the Ubiquiti Unifi
AP range (https://www.ubnt.com/unifi/unifi-ap/). Highly recommended.

No - I've never bought one from my ISP. They don't issue "free" routers.
> 1a) If no, what do you use and why?
I started off with a non-WiFi ADSL 1 router that I bought for about ?230
back in 2002. The firewalling was very rudimentary (a positive for my
intended use at the time) stateless firewalling, so I had a multi-homed
Linux firewall behind it. I later added a WiFi router connected to one of
its interfaces. Its power regulation died, so I'm now using a TP-Link router
in its place. I've also since replaced with ADSL router with a Netgear
ADSL2+ router that I got from a charity shop for about a tenner and has
worked fairly flawlessly. It's a bit flakey renegotiating connections now
I'm running at full-rate ADSL2+, but other than that it's been as good as
gold. Horribly insecure firmware, mind, but a bit of judicious filtering
sorts that out, mostly. It also has WiFi, but I usually leave it disabled,
except for guests, as it's outside my firewall.

There aren't (m)any ADSL routers that have alternate firmware that supports
the included ADSL modem. I have considered using DDWRT on the TP-Link so
that I can turn off masquerade NAT (as I was able to on its Sitecom
predecessor).

FTP, WiFi Analyzer for Android
(<https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer>).

My home is a converted church, so whilst the exterior walls are thick stone,
the interior walls are modern plasterboard. A single AP covers virtually my
entire home, so no.

A fairly central position, compromised by things like cabling and not
wanting to wall or ceiling mount it.
