README for Debian package of procps
ipv6 sysctl keys
Modern Debian kernel packages have the IPv6 module compiled in by default.
This means that the /proc/sys/net/ipv6 directory exists when the procps
startup script runs.
However if you make your own kernel then you may make ipv6 a module and
get a race condition between the netbase and procps startup scripts. This
is because netbase, by default, causes ipv6 module to be loaded but
they don't (and cannot) depend on each-other.
The solution is to either:
- Not put ipv6 keys into /etc/sysctl.d/* or /etc/sysctl.conf
- Compile the ipv6 module into the kernel
- Load the module early by putting ipv6 into /etc/modules
- Make a init script dependency by adding netbase to the Required-Start
line in /etc/init.d/procps
pgrep is a new program, using the Unix standard name for something that
greps for processes. If you are looking for Perl compatible regular
expression grep, it is called pcregrep.
