ok that part is pretty straight forward. But maybe I didn't explain myself
properly or ask the question in the right way before so here's another shot.
Scenario: I have one user on my system called TheNerd. I grant him
permissions to write to /dev/sda5 and /dev/sda6. I set up two build profiles
(same as above but for each seperate partition) called partition5 and
partition6. No matter which one I run "TheNerd" can build and then write to
either partition without sudo.
Question 1: What prevents me from messing up one of the build profiles (say
making them both write to /dev/sd6) and overwriting one with the other?
Question 2 (depending on answer 1): Should I create two users on the linux
system for this? i.e. TheNerd5 and TheNerd6 one with write access to
/dev/sda5 and the other with write access to /dev/sda6. This would
essentially prevent me from writing to any partition other than the one that
it's supposed to (so long as access is granted properly and I don't use
sudo).
Question 3: If the multiple user accounts is the way to go... Do I need to
download seperate versions of the source? One for each user? (my guess would
be yes, especially, if I was building gcc2 with one and gcc4 with the other)
Honestly, I am not trying to be difficult. I really am trying to understand
how this is supposed to work. My apologies if I've missed the blatently
obvious.
Thanks
Dennis
