>Description:
At least on my system, it would appear that /libexec/ld-elf.so.1 does not update during a "make installworld" any more. The timestamps of the files would seem to place it right around the time I started to move to 5.3.
While working on a different problem, I stumbled across the fact that my /libexec/ld-elf.so.1 was out of date compared to the rest of the libs (~1.5 weeks). Digging in to it a bit, I tried to replace it from /usr/obj/.../rtld-elf/ld-elf.so.1 by hand.
[root@new] rtld-elf# make install
chflags noschg /usr/libexec/ld-elf.so.1
install -s -o root -g wheel -m 555 -fschg -C -b ld-elf.so.1 /libexec
install -o root -g wheel -m 444 rtld.1.gz /usr/share/man/man1
/usr/share/man/man1/ld-elf.so.1.1.gz -> /usr/share/man/man1/rtld.1.gz
/usr/share/man/man1/ld.so.1.gz -> /usr/share/man/man1/rtld.1.gz
/usr/libexec/ld-elf.so.1 -> /libexec/ld-elf.so.1
[root@new] rtld-elf# ls -l /libexec/
total 292
-r-xr-xr-x 1 root wheel 147704 Oct 21 21:17 ld-elf.so.1
-r-xr-xr-x 1 root wheel 148312 Oct 5 19:21 ld-elf.so.1.old
Brought the machien down to single user mode, and tried it again. Same results, no update. Tried to copy the file with cp (after chflags noschg), and got:
[root@new] /libexec# cp /usr/obj/usr/src/libexec/rtld-elf/ld-elf.so.1 ./
cp: ./ld-elf.so.1: Text file busy
And a quick lsof shows the problem:
[root@] /etc# lsof
lsof: WARNING: access /root/.lsof_: No such file or directory
lsof: WARNING: created device cache file: /root/.lsof_

I had to exec /rescue/tcsh and then /rescue/cp the file before it would take.
I hope I'm not wasting someones time because of some oddity I have with my system, but I suspect this is 5.3 related with the move to a dynamic root.
