So i've been playing with BackTrack quite sometime now and knows allmost
what i should know, but one thing i am not clear about is:

If i have installed BackTrack to my Harddisk (real installation), and i update
f.ex. php & mysql to the newest, install it via pkgtool, then my question is:

When looking in pkgtool i have the old php and also the old mysql package
installed still, though php and mysql IS up2date. (i ran it from console to check).

So here it comes.. My question is: Can i delete the old packages or are
they a form of depency for in this case, PHP & MySQL to be able to work?

Thank you in advance as i am just generally confused about this.
A yes or no is just fine from someone that knows Linux well.


Update: Ok i have been able to find the problem of which i have troubles with:
Code:
# We don't need to remount root directory readonly in Slax, as it's tmpfs
# It could took very long time. So skip remount if cleanup script is found.
# Nevertheless we MUST remount ro if the cleanup script is not found
# (eg. in the case user installed Slax to disk as a real OS using cp).
if [ ! -x /mnt/live/cleanup ]; then
    echo "Remounting root filesystem read-only."
    /bin/mount -n -o remount,ro /
fi
The problem is then that i don't have such a dir named like /mnt/live...

Then i tried adding: (yes i wrote those notes for later use etc).
Code:
# We are remounting the disks manually by using this line,
# the reason why is because this script is looking for a directory
# called live which doesnt exist, so basicly we will fail each time.
/bin/mount -n -o remount.ro /
Now i just found out that i made it wrong by 1 single comma..
And that it should have looked like this instead:


Code:
# We are remounting the disks manually by using this line,
# the reason why is because this script is looking for a directory
# called live which doesnt exist, so basicly we will fail each time.
/bin/mount -n -o remount,ro /
If anyone has a good solution to this then i'll be happy.
But i'll try this yet again, and then i'll come back to this thread.

/Updated, i have begun trying for myself now..
