I needed a reasonably complete development environment including git (which was not already included in my machine).
sudo apt-get git
Then I create my sandbox for my experiments and fill it with the current revision:
$ sudo apt-get git $ cd sandbox $ git clone git://git.ipfire.org/ipfire-2.x.git Initialized empty Git repository in /home/mcon/sandbox/ipfire-2.x/.git/ remote: Counting objects: 39828, done. remote: Compressing objects: 100% (13496/13496), done. remote: Total 39828 (delta 25030), reused 39714 (delta 24959) Receiving objects: 100% (39828/39828), 36.06 MiB | 233 KiB/s, done.

Then, after a LOOOOOONG time
... Loading xz [ DONE ] Loading zerofree [ DONE ] Loading zlib [ DONE ] ***Verifying md5sums all files md5sum match [ DONE ]
Now we need to get the toolchain, which cannot be built on a 64bit machine (it is a good idea to get it anyways, since compilation time is substantial).
$ linux32 ./make.sh gettoolchain Nov 15 20:03:22: Load toolchain tar.gz for i686 Nov 15 20:06:04: toolchain md5 ok
Notice I used linux32 to pretend I'm on a 32bit O.S., but I'm still working as a normal, non-privileged user. This will change shortly because the build engine needs root privileges.
Now we are all set to start the first, normal compilation:

Oops, what went wrong?
It turns out it's a problem of interaction with ubuntu/gnome handling of mounted filesystems: when a filesystem is mounted ubuntu scans it to present it in the “Places” menu. If it will be unmounted too soon it may still be “busy”.
This may be cured inserting a delay in the right place i.e.:
…/lfs/flash-images#170 should become:
sed -i -e "s|6:2345:respawn:|#6:2345:respawn:|g" $(MNThdd)/etc/inittab sed -i -e "s|#7:2345:respawn:|7:2345:respawn:|g" $(MNThdd)/etc/inittab sleep 10 #<-- this line added by MCon umount $(MNThdd)/boot umount $(MNThdd)
Restart the build. This time everything is fine:
... installer [ ipfire ] [ 0 ] [ DONE ] initrd [ ipfire ] [ 0 ] [ DONE ] *** Building packages (Last stag version) options time (sec) status strip [ ipfire ] [ 49 ] [ DONE ] Generating packages list from logs [ DONE ] cdrom [ ipfire ] [ ED=full ][ 140 ] [ DONE ] usb-stick [ ipfire ] [ ED=full ][ 22 ] [ DONE ] flash-images [ ipfire ] [ ED=full ][ 213 ] [ DONE ] core-updates [ ipfire ] [ 2 ] [ DONE ] 7zip [ 4.65 ] [ 0 ] [ DONE ] alsa [ 1.0.23 ] [ 1 ] [ DONE ] ... watchdog [ 5.9 ] [ 0 ] [ DONE ] xfsprogs [ 2.9.4 ] [ 0 ] [ DONE ] xvid [ 1.2.1 ] [ 0 ] [ DONE ] xen-image [ ipfire ] [ ED=full ][ 200 ] [ DONE ] Generating files list from logs [ DONE ] *** Checking Logfiles for new Fi versionge options1 s time (sec) status Changes in cdrtools-2.01.01 check rootfile! ***Build is finished now and took 0 hour(s) 12 minute(s) 24 second(s)!
At this point you have a completely rebuilt IPFire and we can turn to building something new.
