[cape2.sh] - jemalloc error

Prerequisites

Please answer the following questions for yourself before submitting an issue.

• I checked to make sure that this issue has not already been filed
• I’m reporting the issue to the correct repository (for multi-repository projects)
• I read my log of instalation, all issues will be closed if you don’t do your part of work
• I understand that reporting issue related to any instalation script without instalation log is useless and will be closed

Expected Behavior

jemalloc should install cleanly without any errors

Current Behavior

the execution of cape2.sh ends with an error regarding jemolloc ln: failed to create symbolic link '/usr/lib/x86_64-linux-gnu/libjemalloc.so': File exists

Failure Information (for bugs)

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

1. pull down kvm-aemu.sh
2. run sudo ./kvm-qemu.sh all <username> | tee kvm-qemu.log
3. reboot
4. pull down capev2.sh
5. run sudo ./cape2.sh base cape | tee cape.log
6. observe error at the very end of the execution of cape2.sh

Context

I believe this is a result of running kvm-qemu.sh which installs jemalloc in a different manner, thus resulting in a conflict.

https://github.com/doomedraven/Tools/blob/41bdab856c6bb9e5a559d77606aea8101a5a94f0/Virtualization/kvm-qemu.sh#L774-L778

I suspect reusing the logic from kvm-qemu.sh is a solution, though I’m not confident if that’s the best solution. I am happy to submit a PR with some direction.

As a sidenote, though I don’t think it matter here, I also observed that the file installed via the package in kvm-qemu.sh is different than the one attempted to be symlink’ed in cape2.sh

# existing symlink
> ls -lhntra /usr/lib/x86_64-linux-gnu/libjemalloc.so
lrwxrwxrwx 1 0 0 16 Apr  2  2020 /usr/lib/x86_64-linux-gnu/libjemalloc.so -> libjemalloc.so.2

# md5 of existing symlink
> md5sum /usr/lib/x86_64-linux-gnu/libjemalloc.so.2
d13aabd3e907425ee2efd7098085eb10  /usr/lib/x86_64-linux-gnu/libjemalloc.so.2

# md5 of attempted symlink
> md5sum  /usr/local/lib/libjemalloc.so

ya i see many people getting this problem with jemalloc, the easier is just add options to apt to overwrite the file and forget, i will add that to both scripts today or tomorrow, thanks

just tested it from a snapshot taken just after running kvm-qemu - looks good to me!

Thanks a bunch for all the work you put into this -it has saved me so much time!
