/var/tmp/pkgrecv-* directories left behind After 12.2.2 Upgrade........

It would appear as if the Upgrade process from 12.2.1 to 12.2.2 left behind 40+ directories (with content)

using close to 3GB space.

drwx------   5 root	sys	6 Jun 13 17:50 pkgrecv-1s0Rhl
drwx------  51 root	sys	51 Jun 13 18:29 pkgrecv-4hNzK0
drwxr-xr-x   2 root	sys	2 Jun 13 18:46 pkgrecv-57IrUZ
drwxr-xr-x   2 root	sys	2 Jun 13 18:16 pkgrecv-5Ynv5n
drwxr-xr-x   2 root	sys	2 Jun 13 18:31 pkgrecv-6xUF8T
drwx------   5 root	sys	6 Jun 13 18:02 pkgrecv-ASSnkd

Once Ops Center has been successfully upgraded and running, can these directories safely be removed???

   thanks;
