[request-sponsor] Request Sponsor Bug : 6638873 :usermod -m could optimize the move

[Avinash Joshi]

Hi.

Rishi M Nair (OS0148) and I Avinash Joshi(OS0142) would like to work on the
bug 6638873. We will send the fix at the earliest.

Bug ID - 6638873
Synopsis - usermod -m could optimize the move
Category:Subcategory - utility:security

About the bug:

I just wanted to know how to rename a directory.
For moving the dir, there is a built in function ret =
move_dir(pstruct->pw_dir, dir, logname); which is defined in
usr/src/cmd/oamuser/user/movedir.c

Is there a similar function that renames a directory?

If so pls let me know. Or do we need to create a new function that renames a
directory?

And if not, cobble something together with posix_spawn and "mv(1)".

That would be better than the current

system("cd src && find . -print | cpio -m -pd dest");

(I'm the poor schmuck who filed this bug after having to wait 15
minutes for it to do this when a simple rename would have sufficed.)

As the comments in the bug say, though, any fix ought to handle
the zfs case properly as well.

If the new name is on the same filesystem, see the rename(2) man page.
