:fur such a config there is no need to reserve 10% unused.<br>
:just add TRIMming b partition at every boot. swap would rarely be full.<br>
<br>
</div></div> Yes, very true. swap can be TRIMmed on every boot and in most<br>
situations this will leave enough unallocated space.<br>
<br>
In my example I totally forgot to include an 'unused' partition to<br>
hold the reserved area, too, but just having a larger swap partition<br>
and TRIMming it on boot probably works even better.<br>
<br>
The -e option to swapon will trim swap. Hmm.... our rc scripts don't<br>
provide a way to override that to add the -e.<br><span><font color="#888888"><br>
