>Environment:

	
	Current system.

>Description:

	
	o I have 2 partitions ( /, /usr)
	o I made backups of / and /usr onto one tape.
	  First / then /usr.
	o A make install under /usr/src/lib corrupted my libc.so.2.1
	o After reboot all shared bins exited with Sig11's.
	o I couldn'd delete libc.so.2.1 'cause of the immunitable flag.
	o Clearing the flag was impossible 'cause of shared chflags.

The mt is independent of the chflags problem.
	o I could not wind tho the 2'nd backup on the Tape (the /usr backup)
	  'cause of the shared mt.

>How-To-Repeat:

	
	See above.

>Fix:
	
	
	Make mt and chflags at least static.
	mt should go into /sbin cause it is too essential for recovery.
	chflags should also go into /sbin 'cause progs under / have the
	immuntable flags set too and could therefore not be replaced if
	they where corrupt.
