Force early initialization of the resolver library, since the resolver
|
|
configuration files will no longer be available once sshd is chrooted.

Avoid sshd, cron, syslogd and inetd to be killed under high-pressure swap
|
|
environments.
|
|
Please note that this can't be done while such processes run in jails.
|
|
|
|
Note: in future it would be interesting to find a way to do that
|
|
selectively for any desired proccess (choosen by user himself), probabilly
|
|
via a ptrace interface or whatever.

Enhance r199804 by marking the daemonised child as immune to OOM instead
|
|
of short-living parent. Only mark the master process that accepts
|
|
connections, do not protect connection handlers spawned from inetd.
