[systemd-devel] systemd and mysql with large memory pages

[Reindl Harald]

with sysv/lsb you could include the follwoing script via "source"
and hughe TLB in mysqld worked like a charme

[root at rh:~]$ cat /etc/my.memory.cnf
# Large-Memory-Pages
echo 200 > /proc/sys/vm/nr_hugepages
echo 27 > /proc/sys/vm/hugetlb_shm_group
echo 2097152 > /proc/sys/kernel/shmall
ulimit -l unlimited
ulimit -n 30000

calling this via "ExecStartPre" does not work
so HOW do this on a systemd-environment if your mysqld
has a hughe key_buffer size?
