Subject: [PATCH] Revert "libselinux: restorecon: pin file to avoid TOCTOU
issues"
Content-type: text/plain
This reverts commit 7e979b56fd2cee28f647376a7233d2ac2d12ca50.
The reverted commit broke `setfiles` when it's run from a chroot
without /proc mounted, e.g.
# chroot /mnt/sysimage
chroot# setfiles -e /proc -e /sys /sys /etc/selinux/targeted/contexts/files/file_contexts /
