So, I've been seeing this problem recently where every time I update the
Fedora kernel (currently F27), my grub configuration gets mangled.
I have tuned installed, so it has installed /etc/grub.d/00_tuned, which
executes /etc/tuned/bootcmdline, which in turn spits out when
grub2-mkconfig is run.
### BEGIN /etc/grub.d/00_tuned ###
set tuned_initrd=""
set tuned_params="skew_tick=1"
### END /etc/grub.d/00_tuned ###
However, every time I update the F27 kernel, it mangles the params line, to
something like:
set tuned_params="skew_tick=1"=1"=1"=1"=1"
The =1" can be repeated many times.
