And it seems FreeBSD didn't take care of those. Somehow I "bravely" extracted base.txz - successfully.=20 I wasn't able to isolate the /lib/casper/ issue - which is really a pity si= nce it would have been important for desaster-recovery analysis. Another point is that FreeBSD's kernel is quiet when it fails to boot into = multiuser mode. The phenomenon with the broken installation was, that the kernel stop= ped issuing anything after USB subsystem has been started. Pluggin and unplugging was r= eported, but the boot didn't proceed. Somehow this is annoying. Also, with CURRENT FreeBSD 12.0-CURRENT #75 r327948: Sat Jan 13 23:00:08 C= ET 2018 amd64 up and running again, there are some strange leftovers in /usr/lib: find ./ -ctime +5 -a -name "*.a" -exec ls -l {} \; -r--r--r-- 1 root wheel 173698 Dec 23 23:02 ./libmlx5.a -r--r--r-- 1 root wheel 75698 Dec 23 23:02 ./libibnetdisc.a -r--r--r-- 1 root wheel 43516 Dec 25 03:49 ./libcxgb4.a -r--r--r-- 1 root wheel 6044 Dec 23 23:02 ./libnandfs.a -r--r--r-- 1 root wheel 6580 Dec 23 23:02 ./libnandfs_p.a -r--r--r-- 1 root wheel 86580 Dec 25 03:49 ./libosmcomp.a -r--r--r-- 1 root wheel 22104 Oct 31 13:33 ./libibcommon.a -r--r--r-- 1 root wheel 69812 Dec 23 23:02 ./libibumad.a -r--r--r-- 1 root wheel 105084 Dec 25 03:49 ./libibverbs.a -r--r--r-- 1 root wheel 182118 Dec 23 23:02 ./libibmad.a -r--r--r-- 1 root wheel 67548 Dec 23 23:02 ./libmlx4.a -r--r--r-- 1 root wheel 51190 Oct 16 22:31 ./libmthca.a -r--r--r-- 1 root wheel 125960 Dec 23 23:02 ./libopensm.a -r--r--r-- 1 root wheel 39574 Dec 23 23:02 ./libosmvendor.a -r--r--r-- 1 root wheel 17466 Dec 23 23:02 ./libibcm.a -r--r--r-- 1 root wheel 62058 Dec 23 23:02 ./librdmacm.a -r--r--r-- 1 root wheel 112430 Oct 31 13:33 ./libibsdp.a Those files aren't addressed by "make delete-old-libs" and some of them see= m to belong to outdated or switched off portions of the tree.
