How can I tell how Red Hat was installed? (typical or custom)
 

I have a Red Hat Enterprise Linux 4 server that came pre-installed from Dell.

I need to find out how they installed the OS. (Typical, Custom, or Full). I heard that you can look at the anaconda file and I've edited that but I can't tell.

Any ideas??

Call and ask, most places install everything. You can create a list of what is installed;

rpm -qa --qf="%{n}-%{v}-%{r}.%{arch}.rpm\n" | sort > Installed.txt

If the line count is about 2100 or more then it is likely that everyting was installed, around 1200 more or less then it is likely that a typical install. All bets are off if the is a mixed mode( both 32-bit[x86] and 64-bit[x86_64] ) installation.
