Check write permissions in parent directory for file delete

[Sergey Ablalimov]

Hello.

I am using IMFS as a base file system. And I do following operations:
---------------------------------------------------------------
RTEMS SHELL (Ver.1.0-FRC):/dev/console. Nov  9 2003. 'help' to list commands.
shel [/etc] $ whoami
ant
shel [/] $ ls
drwxr-xr-x   1   root   root        5092 Jan 01 00:00 dev/
drwxrwxrwx   1   root   root        3484 Nov 02 22:28 disc/
drwxr-xr-x   1   root   root        1340 Nov 02 22:28 etc/
3 files 9916 bytes occupied
shel [/] $ cd etc
shel [/etc] $ ls
-rw-r--r--   1   root   root          90 Nov 02 22:28 passwd 
-rw-r--r--   1   root   root         117 Nov 02 22:28 shadow 
-rw-r--r--   1   root   root          42 Nov 02 22:28 group 
-rw-r--r--   1   root   root          34 Nov 02 22:28 issue 
-rw-r--r--   1   root   root          28 Nov 02 22:28 issue.net 
5 files 311 bytes occupied
shel [/etc] $ rm issue
shel [/etc] $ ls
-rw-r--r--   1   root   root          90 Nov 02 22:28 passwd 
-rw-r--r--   1   root   root         117 Nov 02 22:28 shadow 
-rw-r--r--   1   root   root          42 Nov 02 22:29 group 
-rw-r--r--   1   root   root          28 Nov 02 22:28 issue.net 
4 files 277 bytes occupied
shel [/etc] $ 
--------------------------------------------------------------------
I'm not root. I don't have permissions for write in /etc directory, but
I can delete files from /etc.
I see in file "cpukit/libcsupport/src/unlink.c". There are no support 
for check write permissions in parent directory.
Is this RTEMS error?
