Old software gone after upgrade?
Didn't know if this was a "valid" question for Software, and since I still consider myself a newbie at Linux, I posted it here.
Here it goes:
Eventually I want to compile my own, optimized, 2.6.x-kernel for one of my machines.
To do this some software on the machine I want to use for compilation has to be upgraded.
One of these programs is "e2fsprogs". The installed version was 1.27. Minimum requirement was 1.29. I went and installed version 1.38 successfully, that is, "tune2fs" returns version number 1.38 instead of the earlier 1.27, so one can assume that the install went OK.
My question is: What happens to the old software? Is it replaced (where necessary) by new components, or is it left in place and will it "clutter up" my hard disk? Is this generally the case, and not only for "e2fsprogs"?
Not that I have a shortage in disk space, but I just would like to know.
Thanks in advance !!
