To list the files in a package, use the repoquery utility, which is included in the yum-utils package.

For example, the following command lists the files that the btrfs-progs package provides.

# repoquery -l btrfs-progs
/sbin/btrfs
/sbin/btrfs-convert
/sbin/btrfs-debug-tree

Note

yum makes no distinction between installing and upgrading a kernel package. yum always installs a new kernel regardless of whether you specify update or install.
