Debian 7 - nastaveni system environment

Dobry den,

prosim o radu. Zhruba jeden mesic mam problem s instalaci a aktualizaci z repozitare. Problem je v tech instalacich, ktere vytvareji noveho uzivatele. Jedna se o debian 7.

root@test:~# aptitude upgrade

The following partially installed packages will be configured:
  dbus dbus-x11 
No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B of archives. After unpacking 0 B will be used.

root@test:~# printenv | grep NAME_REGEX
NAME_REGEX=^[a-z][-a-z0-9]*$

Kdyz chci pridat uzivatele, napriklad franta.druhy, tak je --force-badname ok, ale do aptitude to nezadam. Co a jak mam nastavit, aby me aptitude bral vazne? Zjistil jsem, ze pri standartni (nove) instalaci promenna NAME_REGEX neexistuje a pritom vsechno funguje spravne.

Myslim, ze problem mohl zacit v dobe, kdy jsem pridaval uzivatele s teckou (franta.druhy). Parametr --force-badname je neco, co jsem se tehdy obaval pouzit, a tak jsem si hral s promennou NAME_REGEX. Stejne jsem nakonec --force-badname musel pouzit.

Google moc nepomohl, vsude pisou, ze mam nastavit NAME_REGEX. Ale uz ne jak.

Nastavuju to pres export:
root@test:~# export NAME_REGEX="^[a-z][-a-z0-9]*$"

Myslim, ze takhle nastaveny NAME_REGEX by mel pro aptitude bohate stacit.

Co delam blbe?
