Description Alan 2003-09-20 23:40:56 UTC 
/etc/init.d/evms (evms 2.0.1) and /etc/init.d/checkfs (baselayout 1.8.6.10-r1)
only check for /sbin/evms_activate before running evms_activate, and if the
kernel does not support evms (ie: a non-gentoo-sources kernel such as
ac-sources) there is a large and ugly error displayed.  Cosmetic I guess, but
something that could be fixed I think.  Just check if /proc/evms (or whatever
the kernel module creates) exists as well as /sbin/evms_activate before running it.

I'd provide a patch but I don't have a kernel evms enabled system here to see
what the script could check for to see if it exists. 

Reproducible: Always
Steps to Reproduce:
1. run a non-evms kernel such as ac-sources
2. have evms package installed
3. boot up and observe the ugly boot up messages as it tries unsuccessfully to
run evms_activate

Actual Results:  
ugly error messages

Expected Results:  
not run evms_activate if the kernel wasn't evms enabled.

no idea why I got this bug...
Comment 2 Jeremy Huddleston (RETIRED) gentoo-dev 2004-06-13 13:33:31 UTC 
evms2 is userland-only and just uses the device-mapper code in the kernel...
