Title:
Some sysctl's are ignored on boot
Status in procps package in Ubuntu:
Confirmed
Bug description:
Binary package hint: procps
/etc/init.d/procps.sh comes too early in the boot process to apply a
lot of sysctl's. As it runs before networking modules are loaded and
filesystems are mounted, there are quite a lot of commonly-used
sysctl's which are simply ignored on boot and produce errors to the
console.
Simply renaming the symlink from S17 to > S40 probably isn't a great
solution, as there are probably folk who want and expect some sysctl's
to be applied before filesystems are mounted and so on. However,
simply ugnoring something as important as sysctl settings isn't really
on. Administrators expect the settings in /etc/sysctl.conf to take
effect.
One sto-gap solution would be to run sysctl -p twice; once at S17 and once at S41. There may still be some warnings and errors, but everything would be applied. A different, more complex approach might be to re-architect the sysctl configuration into something like;
/etc/sysctl.d/$modulename
and have the userland module-loading binaries take care of applying
them after modules are loaded. Though this may take care of explicitly
loaded modules only, I'm not sure.
Incidentally, /etc/sysctl.conf still refers to
/etc/networking/options, but hasn't that been deprecated?
