@aayushrautela try the latest CI build to see if your problem got fixed. |

I think the issue is init relabels xposed_file when doing restorecon on /data, which is usually performed during ota. That's why magisk_file is often used in that dir. |
The init process may relable SELinux context, which can be prevented by marking the context xposed_file with type system_file_type. See https://cs.android.com/android/platform/superproject/main/+/main:system/sepolicy/private/init.te;l=335

User has reported `dex2oat` failure with SELinux log:
```
W dex2oat64: type=1400 audit(0.0:922): avc: denied { read } for path="/data/adb/modules/zygisk_lsposed/bin/liboat_hook64.so" dev="dm-58" ino=91204 scontext=u:r:dex2oat:s0 tcontext=u:object_r:adb_data_file:s0 tclass=file permissive=0
```
Hence, we now set the SELinux context of `liboat_hook.so` in Dex2OatService.
Moreover, by the pull-request #194, we have to move `putenv` out of the if block by testing.
Indeed, if we call `putenv` inside the if block, then it is no longer valid out of the block.
