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.
