Subject: Autofs problem while using new nfs-utils package
Date: Sat, 6 Oct 2007 02:19:20 -0230	[thread overview]
Message-ID: <200710060219.20536.mike@cs.mun.ca> (raw)

I just emerged the latest gentoo release of the nfs-utils package, 
nfs-utils-1.1.0-r1.ebuild.  I found that the autofs code did not work for my 
diskless computers that have a readonly /etc directory with a /etc/mtab 
symbolically linked to /proc/mounts.  This was because the creation of the 
mtab lock file /etc/mtab~nnnn failed.  I noticed that in the update_mtab() 
function, a check was put in to acertain whether this situation existed and 
silently carried on whereas the add_mtab() function did not perform the check 
and consequently failed.  My simple minded fix was to add the the same check 
to add_mtab() as can be seen in the context diff below.  Automounting worked 
fine after the fix was applied.   Hopefully some fix will make its way into 
the authoratative release so that I do not have to patch my code locally.

Thanks,

Michael Rayment
