If I set static route to some network that go through alias
this route will not be set because there is line in
/etc/sysconfig/static-routes:
any net 194.108.45.16 netmask 255.255.255.240 gw
194.108.45.131

so /etc/sysconfig/network-scripts/ifup-routes can't set up
this route (this script depend on eth1:1 instead of word
'any' at the beginnig of the line above - linuxconf gives
parameter eth1:1).

The solution is to set this route with proper interface (ie.
alias - eth1:1) to the begging of the line or allow
linuxconf to generate word 'any' to satisfy with script
(which doesn't seem good - there will be an error message if
any of 'any' routes will be already set at this moment.

This problem seems to be more complex so this is simplest
way I think.
