Bug 201750 – sys-process/daemontools-0.76-r5 - /etc/init.d/svscan starts svscan without cleaning the environment

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Tavin Cole 2007-12-09 09:34:43 UTC]

consider the start() function:

start() {
        ebegin "Starting service scan"
        start-stop-daemon --start --exec /usr/bin/svscan \
                --background --make-pidfile \
                --pidfile /var/run/svscan.pid -- /service
        eend $?
}

i have changed mine to this in order to clean up the environment inherited by all supervised daemons (passing along only PATH):

start() {
        ebegin "Starting service scan"
        env - PATH="$PATH" start-stop-daemon --start --exec /usr/bin/svscan \
                --background --make-pidfile \
                --pidfile /var/run/svscan.pid -- /service
        eend $?
}

even this is a bit weird, you wind up with a PATH like this:

PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/sbin:/bin:/usr/bin:/sbin:/usr/sbin

apparently somewhere during system init the PATH entries get duplicated.

No idea what installs /etc/init.d/svscan; reopen with exact ebuild name and version.

[Comment 2 Tavin Cole 2007-12-09 09:40:37 UTC]

sys-process/daemontools-0.76-r5

there was no input field for that in the bug submission form.

Thanks.

this is already fixed in baselayout-2 with env whitelisting
