* updatehome - Update the current label's $HOME copy and link files.
*
* Update home reads the user's minimum label copy and link
* control files (.copy_files and .link_files) which contain a list
* of files to be copied and symbolically linked from the user's minimum
* label $HOME to the user's current label's $HOME.
*
* This is done by the Trusted Solaris dtsession whenever a
* newly labeled workspace is created so that the user's favorite
* files are available for use. For example the user probably
* wants a symlink to .profile, .login, .cshrc, .exrc, .mailrc, ~/bin,
* ... . updatehome provides a convient mechanism for accomplishing
* this. The user may add any set of files either to be copied
* (.copy_files), or symbolically linked (.link_files).
*
* Files should not include embedded MLDs.
*
* Entry options = c, if replace existing current label $HOME copies
* (default is to ignore existing).
* d, if to print debug trace msgs (internal use only).
* i, if to ignore errors encountered (default is to
* abort).
* m, if to suppress error diagnostics -- perror
* (internal use only).
* r, if replace existing current label $HOME copies or
* symbolic links -- implies c and s (default is to
* ignore existing).
* s, if replace existing current label $HOME symbolic
* links (default is to ignore existing).
*
* Exit stderr = diagnostic messages.
* exis status = 0, no errors noted.
* 1, if errors noted.
*
* Calls __setupfiles (which does all the real work).
*/
/*
* There is a private contract between __setupfiles in this
* directory and login. Changes made to __setupfiles may need to be
* reflected in the source for login.
