That's not really true.. 64MB is the default maxbytes if you don't
provide a -m setting. That being said I believe that it is impossible to
"auto-tune" this setting, because you don't know if the user will be
using the machine as a dedicated memcached server or just share some of
the spare memory in the box. I believe that the end user _has_ to
manually set this option for the instance so any default is as good as
the other...

You can do that now...

No, if you just edit the smf configuration and adds the options it will
automatically work:
example% svccfg
svc:> select memcached
svc:/application/database/memcached> setprop memcached/options=("-u"
"myuser" "-m" "1024")
svc:/application/database/memcached> quit
example% svcadm refresh memcached
This will cause memcached to be started as:
memcached -u noaccess -u myuser -m 1024
The "-u noaccess" will be overridden by the "-u myuser" resulting in
that the service will run as myuser instead of noaccess.
The current patch will allow you to install memcached and enable it
without touching anything. That will result in running as noaccess with
64MB and 4 threads.
Cheers,
