In order to keep only 3 kernel images on a CentOS 7 I edited /etc/yum.conf and I put installonly_limit=3 This parameter works for standard kernel images, but does not work for rescue images: $ ls -al /boot/vmlinuz* -rwxr-xr-x 1 root root 5027376 May 13 20:46 /boot/vmlinuz-0-rescue-2554e2ffad84452bb07401bed0a61089 -rwxr-xr-x 1 root root 3084288 Jun 27 06:42 /boot/vmlinuz-0-rescue-2be43759d5354c5a84125dea5b4a02ab -rwxr-xr-x 1 root root 5029136 Mar 18 05:18 /boot/vmlinuz-0-rescue-3871136569fb49cb934a276af5e09b32 -rwxr-xr-x 1 root root 5029008 Mar 31 19:54 /boot/vmlinuz-0-rescue-ca5579e88a014362836fa90f4aa34248 -rwxr-xr-x 1 root root 5029744 Aug 6 16:31 /boot/vmlinuz-0-rescue-e2ae4db2b909488088e78ac4064661d2 -rwxr-xr-x 1 root root 5029744 Aug 6 03:15 /boot/vmlinuz-3.10.0-229.11.1.el7.x86_64 -rwxr-xr-x 1 root root 5027376 May 13 12:15 /boot/vmlinuz-3.10.0-229.4.2.el7.x86_64 -rwxr-xr-x 1 root root 5029200 Jun 24 00:15 /boot/vmlinuz-3.10.0-229.7.2.el7.x86_64 Is there a way to keep rescue images within a certain limit?
