Is maximum swap usage tunable?

[Mike]

fwiw... here is the script that I use to initialize the RPi3 after I
install the image file.


=====

#! /bin/sh

# this script preps the Raspberry Pi for use

# sequence is:
# - find and load the image
# - boot
# - switch over to ssh, and upload this script
# - log in, su to root, and run this script




#

echo "setting timezone"
tzsetup
#
echo " "
echo "removing freebsd account"
cd /tmp
pw userdel -n freebsd -r
#
echo " "

User=test
UserName="Test User"

echo "adding ${User}"
pw groupadd -n ${User} -g 1001
pw useradd -n ${User} -u 1001 -g 1001 -G wheel -c "${UserName}" \
   -md /home/${User} -M 755 -w no -s /bin/tcsh

echo "setting password for root"

/usr/bin/passwd ${User}

pw usermod root -c rpi3 root

ln -s /usr/lib/libarchive.so /usr/lib/libarchive.so.6

test ! -d /usr/local/etc && mkdir -p /usr/local/etc
