Bug 93241 – /lib/rcscripts/addons/dm-start.sh uses here documents; doesn't work with read-only /

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description chia.penguin 2005-05-19 12:58:39 UTC]

/lib/rcscripts/addons/dm-start.sh uses here documents (cmd <<<input).  Since
this is run before other filesystems get mounted (ie, a rw /tmp), the commands
that use the here documents fail on systems with a read-only /.

Reproducible: Always
Steps to Reproduce:
