-After installing from our tor iso:
-
-- set up dedicated /srv disk, if we have one
-
-- make a swapfile (either on / or on /srv if that's a dedicated FS)
-  cd /srv && [ -e lost+found ] &&
-  dd if=/dev/zero of=swapfile bs=1024k count=4096 &&
-  chmod 0 swapfile &&
-  mkswap swapfile &&
-  echo "`readlink -f swapfile` none swap sw 0 0" >> /etc/fstab &&
-  swapon -a
