ezchroot's Issues

[Bug] [Fatal] Opening/Locating/Copying libraries is broken in macOS Big Sur.

So we got a new UI but we algo got a new way of how system libraries work:

• Default system libraries are no longer present in the filesystem they are cached.

According to Apple:

New in macOS Big Sur 11 beta, the system ships with a built-in dynamic linker cache of all system-provided libraries. As part of this change, copies of dynamic libraries are no longer present on the filesystem. Code that attempts to check for dynamic library presence by looking for a file at a path or enumerating a directory will fail. Instead, check for library presence by attempting to dlopen() the path, which will correctly check for the library in the cache. (62986286)

This means doing the syscall that we normally do when copying files open() will fail with "No such file or directory" apparently Apple solution is so syscall dlopen() thing I will look into for fixing this issue.

dyld: Library not loaded: /System/Library/Frameworks/NetFS.framework/Versions/A/NetFS

Hi, I was trying to add /usr/bin/codesign, /usr/bin/security into coreApplication lists, the create command was success, but I can't start them with missing framework error:

sh-3.2$ codesign
dyld: dyld cache load error: shared cache file open() failed
dyld: Library not loaded: /System/Library/Frameworks/NetFS.framework/Versions/A/NetFS
  Referenced from: /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/CarbonCore.framework/Versions/A/CarbonCore
  Reason: image not found
Abort trap: 6

I copy the whole /System/Library/Framerowks, /System/Library/PrivateFramerowks, /usr/lib, and the next error is:

sh-3.2$ security create-keychain -p 123456 test.keychain
security: SecKeychainCreate test.keychain: A Module Directory Service error has occurred.

I have few questions:

1. Is it okay to add some binary into coreApplications which is essential for iOS develop(codesign, security, and more)? or can we manually provide the list as an argument to you?
2. The second error seem that I need to launch some services, do you have any ideas?

My final goal is to create a seprate iOS build enviroment, making xcode, code signing, cocoapods, jenkins works, hope your project can help, thanks :)
