 Description	

rpm errors about the /proc filesystem

bash-4.2# rpm -qa |grep which
warning: Failed to read auxiliary vector, /proc not mounted?

This appears to be one of the items fixed in rpm 4.11.2 per release notes http://www.rpm.org/wiki/Releases/4.11.2

Fix unnecessary /proc dependency if getauxval(3) is available

Can we get this fixed in 4.11.1 as an errata?

---------------

Looks like the new rpm version expects some /proc population (in this case /proc/self/auxv). There is minimal /proc in the target aos image when building
bash-4.2# ls /proc/
modules mounts

Found this snippet of rpm source from google:
++#if defined(_linux_)
++/**
++ * Populate rpmat structure with parsed info from /proc/self/auxv
++ */
++static void parse_auxv(void)
++{
++ static int oneshot = 1;
++
++ if (oneshot) {
++	rpmat.platform = "";
++	int fd = open("/proc/self/auxv", O_RDONLY);
++
++	if (fd == -1)
{ ++	 rpmlog(RPMLOG_WARNING, ++	 _("Failed to read auxiliary vector, /proc not mounted?\n")); ++ return; ++	}
else {
++	 ElfW(auxv_t) auxv;
++	 while (read(fd, &auxv, sizeof(auxv)) == sizeof(auxv)) {
++ switch (auxv.a_type)
++
{ ++ case AT_NULL: ++ break; ++ case AT_PLATFORM: ++ rpmat.platform = strdup((char *) auxv.a_un.a_val); ++ break; ++ case AT_HWCAP: ++ rpmat.hwcap = auxv.a_un.a_val; ++ break; ++ }

++	 close(fd);
++	}
++	oneshot = 0; /* only try once even if it fails */
