Adding lines to inittab

[Neil McGuire]

Perhaps this question is better suited to OpenEmbedded than here, but I’m trying to make it so my rootfs has the following line in /etc/inittab, but can’t figure out how to do it short of manually editing the file before packaging it into a .jffs2 file.

S1:2345:respawn:/usr/sbin/pppd call gsm

Any suggestions?

Here’s what I ended up doing inside the .bb file:

pkg_postinst_${PN}() {<br />

#!/bin/sh -e<br />

# Make it run on the machine once installed, not on image packaging<br />

if [ x"$D" = "x" ]<br />

then<br />

# Check to see if pppd is already registered in /etc/inittab<br />

if ! grep /usr/sbin/pppd /etc/inittab<br />

then<br />

echo "Registering pppd for startup."<br />

# operator '>>' appends to an existing file<br />

echo "S1:2345:respawn:/usr/sbin/pppd call gsm" >> /etc/inittab<br />

else<br />

echo "pppd already registered.<br />

fi<br />

else<br />

exit 1<br />

fi<br />

}

Granted, that doesn’t get it into the image, and also didn’t run on its own, but opkg update && opkg upgrade causes it to fire on the next upgrade.
