Hi all, As the maintainer of bcache-tools I ran into the situation that a collegue accidentally removed bcache-tools, resulting in a system that failed to boot after installing and using a new kernel. dnf logs showed that the package had been erased, with a bunch of other packages. It happene

Hi, On bugzilla there was a brief discussion on how to reduce the number of blkid calls during udev rules processing: https://bugzilla.redhat.com/show_bug.cgi?id=1004693 The general idea was to rely on earlier calls to blkid instead of having later rules calling blkid themselves. Specificall
