Dear Colleagues, I've inherited a swapless FreeBSD 11.2 host with no unused disk space. I would like to add some swap to be on the safe side: in case there is a memory leak etc. On the other hand, I don't like to waste several gigabytes on a precious SSD because perhaps the system will never need this swap space anyway. The FreeBSD Handbook prescribes creating a swap file with "dd if=/dev/zero ..." which would waste the space. Is there any good reason I can't just "truncate -s2G /swap0" and make the swap a sparse file? Thanks in advance for any input. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/
