Yes. You can add lines in /etc/sysctl.conf and load them with sudo
sysctl -p
But only kernel parameters that are set under /proc/sys/
And instead of:
$ sudo echo 2048> /proc/sys/dev/hpet/max-user-freq
You can also do:
$ sudo sysctl -w dev.hpet.max-user-freq=2048
This will write an entry in /etc/sysctl.conf
But again this only applies for parameters under /proc/sys/, I have no
idea if there is an equivalent tool to sysctl for parameters under
/sys/class so you'll probably have to script it.
I think you can put it in
$ cat /etc/rc.local
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
echo 2048 > /sys/class/rtc/rtc0/max_user_freq
exit 0
