1) I suppose there is something in /serv/ipfire/trunk/log/_build.installer.log
2) When I see this output:
reiser4progs [ 1.0.5 ] [ 188 ] [ DONE ]
reiserfsprogs [ 3.6.19 ] [ 38 ] [ DONE ]
sysfsutils [ 1.3.0 ] [ 19 ] [ DONE ]
util-linux [ 2.12r ] [ 12 ] [ DONE ]
pciutils [ 2.2.3 ] [ 4 ] [ DONE ]
zlib [ 1.2.3 ] [ 8 ] [ DONE ]
the question arises: who outputs that? In other words, what soft do you run to "o build a linux distribution from source".
3) For me it seems to be an error of the soft from point 2. Please, try to run this "building process" on usual CentOS kernel.
Thank you,
Vasily.
