Package: diffutilsVersion: 3.5HiThe test tests/brief-vs-stat-zero-kernel-lies fails with    cat: /proc/cmdline: Permission deniedif /proc/cmdline exists but is not readable. This is for example the case on a Linux kernel with grsecurity patchset and option GRKERNSEC_PROC_USER enabled.The fix is easy. The script tests/brief-vs-stat-zero-kernel-lies checks in line 13 only for exists (test -f) of $boot (= /proc/cmdline):    test -f $boot || skip_ no $boot filemaking it check for readability (test -r) solves the problem (as the test is now correctly skipped):    test -r $boot || skip_ file $boot not readableKind regardsjulama
