Re: chflags error message

Paul de Weerd
Hi Marcus,

[redirecting to misc@, this is not a bug and all is working as
intended]

By the time your recursive chflags gets to pkg_add, it will already
have the flag.  Note that these flags are per inode, and several files
under /usr/sbin have the same inode:

[weerd@despair] $ cd /usr/sbin; ls -li | grep 134232
134232 -r-xr-xr-x   7 root  bin         1473 Oct 27 03:48 fw_update
134232 -r-xr-xr-x   7 root  bin         1473 Oct 27 03:48 pkg_add
134232 -r-xr-xr-x   7 root  bin         1473 Oct 27 03:48 pkg_check
134232 -r-xr-xr-x   7 root  bin         1473 Oct 27 03:48 pkg_create
134232 -r-xr-xr-x   7 root  bin         1473 Oct 27 03:48 pkg_delete
134232 -r-xr-xr-x   7 root  bin         1473 Oct 27 03:48 pkg_info
134232 -r-xr-xr-x   7 root  bin         1473 Oct 27 03:48 pkg_sign

The recursive operation doesn't pay attention to this implementation
detail, so it first runs chflags against fw_update.  Then when it
finds pkg_add, it'll try to run chflags against it, but now it already
has the flag, so it gives you an error.

You will probably have seen multiple errors while running your
recursive chflags operation.  Same deal there.


Note that running chflags on files in your /usr/sbin directory will
be a problem come upgrade time.  You'll need to remove the flag before
you can upgrade.

Cheers,

Paul 'WEiRD' de Weerd

|

|
|
| Still the schg flag is set.
|
|
| How come I get an error when running recurively but not when I run it on the same single file?

| I hope this will help you and if I have posted to the wrong address I apologize!!

| Please, tell me where to post this if it is wrong!
