Пытаюсь собрать desktop такой коммандой:
$spt -v --arch=i586 --apt-config=/home/stanv/apt_dir_conf/apt.conf
--profile-dir=dvd4 .

Причем:
$ cat ~/apt_dir_conf/apt.conf 
Dir::Etc::SourceList "/home/stanv/apt_dir_conf/sources.list";
Dir::Etc::SourceParts "/var/empty";


[stanv@stanv desktop]$ cat ~/apt_dir_conf/sources.list 
rpm [alt] ftp://salto/branches/4.0 i586 classic

rpm ftp://ftp.altlinux.org/pub/people/boyarsh/repo i586 hasher other kernel
