Aptitude more sophisticated, it registers all the packages and if a package which have installed for dependency resolving purpose and getting unneeded the aptitude removes it automatically. You can even use synaptic a graphical package manager. and read "man aptitude" 3. Ithink the problem isn't a problem. If you are using dhcp ,the dhclient rewrite /etc/resolv.conf on every network setup with the actual informations which have got from the dhcp server.

install? do you actually mean to boot? Open /boot/grub/menu.lst and change 'default' to your second OS starting from 0. For eg: If the entries in your menu.lst are as,

Code:

1. Debian
2. Debian single user mode
3. CentOS
4. Windows

and you want to boot CentOS by default instead of Debian, change Default to 2.

Code:

default 2

xmp? or xpm the splash image? Add splashimage entry as follows, assuming your splash image in in /boot/grub and Debian is in first partition of your harddisk

Code:

splashimage (hd0,0)/boot/grub/splash.xpm.gz

See which entry is RHEL and change the vaule of 'default' accordingly (starting with 0). __________________ A candle looses nothing by lighting other candles. - Khalil Zibran.
