sysctl behaves differently under liquorix
:: Code :: $ inxi -bxx

Under the aforementioned kernels, commands placed inside /etc/rc.local execute normally. But when running under a liquorix kernel, the commands do not seem to execute at all. Scenario: I have these inside /etc/rc.local: :: Code :: $ cat /etc/rc.local
#!/bin/sh -e sysctl -q -w vm.swappiness=10 # disable pause frames ethtool -A eth0 tx off ethtool -A eth0 rx off # enable in-kernel polling echo 3500 > /sys/module/block/parameters/events_dfl_poll_msecs exit 0 Whenever I run the system under the aforementioned kernels, pause frames for eth0 get disabled by querying :: Code :: # ethtool -a eth0:: Code :: # cat /sys/module/block/parameters/events_dfl_poll_msecsWhere can I look in liquorix to troubleshoot this unexpected behavior? UPDATE: It seems that sysctl under liquorix behaves differently. I observed the following dmesg after running :: Code :: # sysctl vm.swappiness
10 # dmesg <snip> nr_pdflush_threads exported in /proc is scheduled for removal sysctl: The scan_unevictable_pages sysctl/node-interface has been disabled for lack of a legitimate use case. If you have one, please send an email to linux-mm@kvack.org. From my /etc/rc.local, i removed the sysctl command and moved it into /etc/sysctl.conf. Now the commands execute normally under liquorix. It seems that the sysctl line errors out somehow, thus not completing the rest of the commands after it, when rc.local is called upon bootup. What could be the cause of this different behavior?
