From: Carlos Santos Date: Mon, 11 Jun 2018 06:00:14 +0000 (-0300) Subject: sysvinit: add an inittab entry to activate swap X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d2a091c96b87c5674754a12ee9055a164270d0eb;p=buildroot.git sysvinit: add an inittab entry to activate swap There is a call to swapoff in the shutdown sequence, so call "swapon -a" on startup. As stated in the swapon man page, All devices marked as "swap" in /etc/fstab are made available, except for those with the "noauto" option. Devices that are already being used as swap are silently skipped. So even if the system has some init script to start/stop swap (e.g. from a rootfs ovelay) calling swapon/swapoff would be harmless.
