Summary: RamFS shows zero st_blocks in fstat (TCB doesn't work)
Product: Sisyphus Reporter: Fr. Br. George <george>

Description Fr. Br. George 2004-02-06 14:33:26 MSK 
When calling fstat64 on some file located on ramfs,
it constantly returns zero in st_blocks parameter.
E.G.
So keeping /etc in ramfs prevented password system from looking in shadow files,
and paswd/login will always fail.

This possibly cause another valuable system components fail.


Steps to Reproduce:
1.mkdir /bup
2.find /etc | cpio -pdm /bup
3.mount -t ramfs none /etc
4. cd /bup/etc
5. find . | cpio -pdm /etc
6. cd /root; strace -vo log passwd
Actual Results:  
passwd: Authentication service cannot retrieve authentication info..
grep fstat log | tail
...
fstat64(... st_blocks=0...)
