Unfortunately, install from GNU coreutils is now unable to install
anything again. I tried both as 'nobody' and as 'root', it doesn't make
a difference:
| # /compat/linux/usr/bin/install -c .libs/libexpat.so.1.8.10 /wrkdirs/usr/=
ports/textproc/linuxsrc-expat/work/stage/compat/linux/usr/lib64/libexpat.so=
=2E1.8.10
| /compat/linux/usr/bin/install: setting permissions for =E2=80=98/wrkdirs/=
usr/ports/textproc/linuxsrc-expat/work/stage/compat/linux/usr/lib64/libexpa=
t.so.1.8.10=E2=80=99: Operation not permitted
=2E. and truss shows this again:
| linux_fsetxattr(0x4,0x401860e8,0x134dd0,0x1c,0x0) ERR#-1 'Operation not p=
ermitted'
This is without the new jail option. When I enable it, it still fails
the same way as 'nobody' (which poudriere uses for building), but works
fine as 'root'.
I assume the fsetxattr call needs some adjustment of error codes as well
to make GNU tools play nice.
Cheers, Felix
