Selinux slow / How to disable selinux labeling from SPEC Was: mv is massively slower on the host rather than in a nspawn chroot, regression somewhere?

Hi, So I have an annoying bug that started near the beginnings of F35. My papirus-icon-theme became very slow to install: https://bugzilla.redhat.com/show_bug.cgi?id=2029709#c18 During the installation, all the files are copied, then renamed by rpm (no idea why it works like this). It works fast in a Mock chroot but incredibly slow on bare metal. I've done a small test of moving files: [root@cassini icons]# mkdir test [root@cassini icons]# for (( i = 0; i < 10000; i++ )) do > test/file_$i; done [root@cassini icons]# cd test On host: time $(for f in *; do     mv "$f" "${f%}.txt"; done) real    2m3,500s user    0m3,966s sys     2m0,431s In nspawn container: <mock-chroot> sh-5.1# time $(for f in *; do     mv "$f" "${f%}.txt"; done) real    0m6.702s user    0m4.237s sys     0m3.344s Since papirus-icon-theme contains more than 100,000 (small) files, it is a problem. One minute of waiting is ok, 20 mn is not. What can cause this? I read that nspawn virtualizes the file system, could it be file system related on the host? (I use btrfs btw) Any input welcome!
