Re: Adding makemandb as build tool for man.db

David Brownlee <[email protected]>
Newsgroups gmane.os.netbsd.ports.mac68k,gmane.os.netbsd.devel.installation
Message-ID <CAGN_6pY7zW15W-qkCSB0doe_DURjbyfgB=Lt1C9PAs=Hgv0DnA@mail.gmail.com> 
What do people think of the following diff to sysinst to add makemandb=NO
to rc.conf on slow or low memory machines:

Essentially adjust_for_low_ram_or_slow_cpu()  would be run just before
md_cleanup_install(), and each md.h defines (or not) SLOW_CPU.
For now this just sets makemandb=NO (leaving nightly cron to update it),
but it could potentially be extended in time.

I'm happy for adjustments on the "'SLOW_CPU" and "not SLOW_CPU" lists - its
just intended as a rough heuristic. There will be some ports who have
machines firmly in both camps.

not SLOW:
alpha amd64 bebox evbarm evbmips hppa i386 macppc ofppc sgimips sparc
sparc64

SLOW:
acorn32 amiga arc atari cats cobalt emips evbppc evbsh3 ews4800mips hp300
hpcarm hpcmips hpcsh landisk luna68k mac68k mipsco mvme68k news68k newsmips
playstation2 pmax prep sandpoint shark vax x68k zaurus

/* Add some settings for arches which define SLOW_CPU *or* when RAM < 64 */

#endif
       add_rc_conf("makemandb=NO\n");
       return 0;
}
