abuild rootbld: abuild-sign can't preserve ownership
When building any aport using abuild rootbld I get the following error during create_apks():
mv: can't preserve ownership of '/home/soeren/src/aports/community/tpm/pkg/.control.tpm/control.tar.gz': Invalid argumentThis error message is emitted by the mv invocation in the following abuild-sign line:
Both files in that line are existing files owned by root:
-rw-r--r-- 1 root root 543 Dec 20 19:31 /home/soeren/src/aports/community/tpm/pkg/.control.tpm/control.tar.gz
-rw-r--r-- 1 root root 949 Dec 20 19:31 /tmp/tmp.hKGmJhSince that mv invocation is executed in a bwrap environment (as created by abuild rootbld) and fakeroot this may be a problem in the handling of lchown (used internally by mv to preserve ownership) in fakeroot? The error message appeared recently and wasn't present previously.
