[syslinux] [PATCH] Create /var/run/tftpd-hpa.pid in standalone mode

[Ferenc Wagner]

This is more a question than a serious proposal.  The name of the pid
file should probably be configurable, and it should be unlinked on
normal termination, but no such thing exists in standalone mode.
SIGTERM and SIGINT should be catched and considered normal, I guess.
