Description Tereza Cerna 2015-10-05 08:26:05 EDT
File /etc/default/grub contain row with variable GRUB_CMDLINE_LINUX_DEFAULT if tuned is installed. If package tuned is uninstall, this row should not be in /etc/default/grub.

There is nonactual regex in %postun.

# rpm -q tuned
tuned-2.5.1-4.el7.noarch

# cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT=
GRUB_CMDLINE_LINUX_DEFAULT="${GRUB_CMDLINE_LINUX_DEFAULT:+$GRUB_CMDLINE_LINUX_DEFAULT }\$tuned_params"

# yum remove tuned 
# rpm -q tuned
balíček tuned není nainstalován

# cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT=
GRUB_CMDLINE_LINUX_DEFAULT="${GRUB_CMDLINE_LINUX_DEFAULT:+$GRUB_CMDLINE_LINUX_DEFAULT }\$tuned_params"

Row GRUB_CMDLINE_LINUX_DEFAULT=... should be removed during uninstall.
Comment 2 Jaroslav Škarvada 2015-10-06 08:24:01 EDT
The tuned footprint in /etc/default/grub was improved to deal with whitespaces, but the clean-up regex in SPEC wasn't updated.
