ever notice when using windows, you feel like you are not in control of your own computer. hehe, under linux there are only a few things you cannot do.
quick quiz to test some peoples knowledge of linux

ahem,

which one of the following can't be done to on linux system but can be down on a freebsd system

A. delete necesary shared libraries
B. unmount a file system in use
C. update core shared libraries
D. make an iso image with a single command

that's an interesting question, and i'd have to guess, since i haven't made an iso image or used BSD.

It could be any of them, i suppose, i'd say that it's not the unmounting one, but that's a guess, as i say i haven't used BSD yet.

And re: control, yes i have noticed that, with diversification of today's technology though, may people actively try not to be in control of their own machine, preferring to have control over only a small part of it's software (but they get angry really quick if they're denied that part!)

yeah, you got it right, its one of the broken features of alot of unix's, but i was reading some of the freebsd documentation, it will let you do that. also the command to make and iso image would be

dd if=/dev/cdrom of=./cdrom.iso

or

cat /dev/cdrom > ./cdrom.iso


also, i learned the hardway and deleted libc6.so   , once, i though i could replace it with a versin of glibc i just compiled /*proof positive that i didn't always know half of what i do now and that anybody can learn*/

also for updating core library's, up2dateing glibc does this.
