In a poudriere jail, during a bulk run, what is the status of /etc/os-release supposed to be?

I tried to look via bulk with -i and what I saw via
interactive commands was:

# ls -ldT /etc/os-release 
lrwxr-xr-x  1 root  wheel  21 Dec  6 00:48:55 2019 /etc/os-release -> ../var/run/os-release

# ls -laT /var/run/
total 28
drwxr-xr-x   5 root  wheel    512 Dec  6 00:50:02 2019 .
drwxr-xr-x  24 root  wheel    512 Mar  9 07:41:50 2019 ..
drwxr-xr-x   2 root  wheel    512 Mar  9 07:41:50 2019 dhclient
-r--r--r--   1 root  wheel    173 Dec  6 00:50:01 2019 ld-elf.so.hints
drwxrwx---   2 root  network  512 Mar  9 07:41:50 2019 ppp
-rw-r--r--   1 root  wheel    197 Dec  6 00:50:02 2019 utx.active
drwxr-xr-x   2 root  wheel    512 Mar  9 07:41:50 2019 wpa_supplicant

So no /var/run/os-release to find:

# more /etc/os-release 
/etc/os-release: No such file or directory

This was based on (from outside that bulk session):

# poudriere version
3.3.99.20190828

# poudriere jail -l
JAILNAME          VERSION      ARCH          METHOD TIMESTAMP           PATH
FBSDcortexA53jail 13.0-CURRENT arm64.aarch64 null   2018-11-18 15:32:34 /usr/obj/DESTDIRs/clang-cortexA53-installworld-poud

where what is at the PATH was based on:

installworld distrib-dirs distribution DB_FROM_SRC=1 DESTDIR=/usr/obj/DESTDIRs/clang-cortexA53-installworld-poud

(for a head -r355027 based context).


This would appear to mean that port builds should
not be trying to use /etc/os-release because
/var/run/os-release is not established in
poudriere-devel bulk build contexts?

I will note that clang-cortexA53-installworld-poud was built via
an amd64->aarch64 cross build, in case that matters for some
reason. ( clang-cortexA53-installworld-poud/ was copied to the
aarch64 system it was intended for. Both contexts use the
/usr/obj/DESTDIRs/ style path prefix. )

I'm not trying to use /etc/os-release directly. I was just
curious what it would appear to contain in such a context.
