[Pkg-samba-maint] Bug#695362: samba-common's dhcp hooks write to /etc/samba breaking ro root

[Andrew Shadura]

Package: samba-common
Version: 2:3.6.6-2
Severity: normal

samba-common provides a dhcp-client hook script,
/etc/dhcp3/dhclient-enter-hooks.d/samba, which apparently writes to /etc
thus breaking boot when the rootfs is read-only.

SAMBA_DHCP_CONF=/etc/samba/dhcp.conf

<...>

echo -n > ${SAMBA_DHCP_CONF}.new
<...>
mv ${SAMBA_DHCP_CONF}.new $SAMBA_DHCP_CONF

It'd be cool if that could be disabled via /etc/defaults, or, better, if
it could detect that location not being writable and not try to write
there if it is.
