How do I make the system-wide default size of tmpfs smaller (or bigger for
I found that for one-time use I can change the size of tmpfs in this
# make tmpfs in /dev/shm 40Mb
mount -o remount,size=40M /dev/shm
Obviously, I can also change fstab
tmpfs /var/volatile tmpfs size=40M
tmpfs /dev/shm tmpfs
size=40M,mode=0777 0 0
tmpfs /media/ram tmpfs size=40M
And, of course, most obviously I can change the source code of the kernel
myself with my bare hands while walking up-hill both ways in the snow on my
netbook with full-20%-size-keyboard and a 1400 baud modem on a 8088
processor in the editor I wrote myself in assembly and punch-cards.
I don't recall seeing the option in make menuconfig
Maybe something in /etc/sysctl.conf?
