Description Christian Holpert 2018-04-12 14:01:02 UTC
In amavisd-new, current version 2.11.0-r3 (and older versions probably), the systemd-unit prohibits write-access to config-files when spamassassin with DCC-Plugin (mail-filter/dcc-1.3.158) is enabled.

Reproducible: Always

Steps to Reproduce:
1.every time a mail is filtered with amavisd-new/spamassassin/dcc
Actual Results:  
error: Apr 12 15:38:49 colin dccproc[1484]: open(/var/dcc/map): Read-only file system

Expected Results:  
No error.

Apr 12 15:38:49 colin dccproc[1484]: open(/var/dcc/map): Read-only file system

colin ~ # ll /var/dcc/map
lrwxrwxrwx 1 amavis amavis 12 19. Mär 09:36 /var/dcc/map -> /etc/dcc/map

mail-filter/dcc-1.3.158 installs its config in /etc/dcc, see ebuild:
moveconf() {
	local into=/etc/dcc/
	for i in $@; do
		mv "${D}${dcc_homedir}/${i}" "${D}${into}"
		dosym "${into}${i}" "${dcc_homedir}/${i}"

/usr/lib/systemd/system/amavisd.service includes 'ProtectSystem=full' which disables write-access on /etc by design.

# /etc/systemd/system/amavisd.service.d/override.conf

will remove the error.

Possible solution: mail-filter/dcc should place config in /var/dcc/etc or amavisd's systemd-unit could be changed as above.

bug-report on redhat on this topic:

for the first solution, this patch might be needed.

I believe we already have the fix for SpamAssassin in place. Reading the source code for "dccproc", it's clear that the map file in question is *not* a configuration file. It's persistent, writable, program data: i.e. the stuff that goes under /var.

So I think the right fix for this is to leave the map file (and anything else that needs to be written at runtime) where it is.

(/var/lib/dcc would be even better IMO)
